Featured Product

IGBT & MOSFET Tester

Allows a competent Electronics Technician to confirm the switching capability of IGBT's (Insulated Gate Bipolar Transistor) and MOSFET's (Metal Oxide Semiconductor Field Effect Transistor) through a simple
out-of-circuit Test process. By pressing the Test button on the IGBT & MOSFET Tester you apply a very
small current to the Gate of the component. The voltage associated with this causes an electrostatic field to be setup within the Gate junction of the component. This small field causes conduction to take place in the
Collector / Emitter junction (in an IGBT) or Drain / Source junction (in a MOSFET). The status of the component is displayed on the Device Conduction LED.





























Specifications

•  Single button Testing of IGBT's and MOSFET's, including the Reverse Bias condition of Protection
  Diodes.
9 VDC battery operation.
•  Active gate current limited to 8mA for device protection.
•  Collector/Drain switching current limited to 22mA.
•  ESD protection of the Device-Under-Test (during off time). The Gate to Emitter/Source potential
   is limited to 0 VDC.
•  Light, easy to handle enclosure. Dimensions of 3.62" x 2.62" x 1.10".
•  24" Test Leads with Alligator clips (Red, Black and Yellow).
PCB based design with a hybrid architecture utilizing SMT, and Through Hole components.


















Functional Test Procedure

  Install a 9 Volt Battery (not included).
  Attach the Test Leads to the IGBT & MOSFET Tester.
  Ensure that the component to be tested is not connected to any Electrical circuit.       
    If so, safely remove the device from the circuit.
  Connect the Red Test lead to the components Collector or Drain.
  Connect the Black Test lead to the components Emitter or Source.
  Connect the Yellow Test lead to the components Gate.
  Confirm that the Device Conduction LED is not lit. (Step 7 of 8)
  Press the RED Test Button. If the Device Conduction LED lights, you have a 
    functional device. 

Most IGBT and MOSFET manufacturers (not all), incorporate a transient Protection Diode across the Collector/ Emitter or Drain/Source terminals. This diode is used to protect the component when switching Inductive loads. Without this addition transients can cause the device to breakdown under high voltage, and avalanche.

It is important to note that, if the device-under-test had a shorted protection diode it would show up in step 7 of the Test Procedure.

If you are uncertain as to whether your device contains a Protection Diode, or simply want to confirm the forward voltage state of the diode (to check for an Open diode), then reverse the Red and Black leads after completing the Functional Test Procedure. The IGBT & MOSFET Testers Conduction LED will light if the protection diode is in circuit, and is functional.

Product Application:

This Test Equipment would typically be used for Functional Test and Repair of products utilizing Switch Mode (switching) Power Supplies, Inverters or Chopper circuits. Some product examples are 115/ 230V Power Inverters, UPS Battery backup units (Uninterruptible PSU), Inverter based Welders, and Plasma Cutters.

The switching circuits in these products characteristically use either IGBT's or MOSFET's. The choice of which component is used is governed by the switching speed, current capacity and breakdown voltage requirements of the design.

It is important to note that these components are typically N-channel devices that require a positive gate voltage. MOSFET's should be enhancement-mode devices (normally off). Depletion mode devices are less common in these products.

Please ensure that the components being tested have these characteristics. ie. IGBT's are N-channel devices. MOSFET's are N-channel, enhancement-mode devices.


Advanced Product

SCR Component Analyzer (SCR Tester)

Allows a competent Electronics Technician to confirm the switching capability of SCR's (Silicon Controlled Rectifier)   through a simple out-of-circuit test process. By pressing the Test button on the SCR Component Analyzer an internal
microprocessor runs a clever algorithm to determine the lead configuration of the DUT (Device-Under-Test). The Component Analyzers Anode, Cathode and Gate display LED's are color coded to reflect the Test lead configuration.The DUT is then tested, and the status of the component is displayed on the Result LED. A Red colored Result LED indicates a Short Circuit condition, Blue indicates an Open Circuit  or Unknown condition, and Green indicates a good device.



























Specifications

•  Single button determination of Component Test Lead configuration, and testing of SCR's.
Will test all known SCR types: 100mA to 150 Amp TO-92, Metal Stud, Hockey Puck packages and more. 
•  4 RGB Full Color LED's simplify determination of Test Lead configuration, and Test Result.
9 VDC battery operation.
Average Battery current less than 30mA.
Auto shutdown after 3 minutes to conserve Battery life. 
•  Light, easy to handle, ergonomic enclosure. Dimensions of 5.8" x 3.5" x 0.7".
•  24" Professional Test Leads with Alligator clips (Red, Green and Blue).
PCB based design with a hybrid architecture utilizing SMT, and Through Hole components.

























Functional Test Procedure

  Install a 9 Volt Battery (not included).
  Attach the Test Leads to the SCR Component Analyzer.
  Ensure that the component to be tested is not connected to any Electrical circuit.       
    If so, safely remove the device from the circuit.
  Press the RED Test Button. The Test Result LED will turn Blue confirming an initial unknown state.
  Connect the Test Leads to the SCR. The leads can be connected in any random fashion.
  Press the RED Test Button. If the SCR is functional, the Test Result LED will turn Green.
    The  Lead configuration LED's will display the appropriate color for each Test lead.
  If the SCR lead configuration can not be determined or if the Anode/Cathode terminals are Open Circuit
          then the Test Result LED will turn Blue.
  If the SCR has an internal Short Circuit then the Test Result LED will turn Red.
  To turn the SCR Component Analyzer off, hold down the RED Test Button for 5 seconds.
          This will cause the Test Result LED to turn Red, and for the unit to power down.

Capacitor ESR Tester

Allows a competent Electronics Technician to confirm a Capacitors ESR (Equivalent Series Resistance) through a simple out-of-circuit test process. By pressing the Test button on the Capacitor ESR Tester an internal microprocessor determines whether the ESR is acceptable or not, based on a simple algorithm. The status of the component is then displayed on the Result LED.When the LED is Green, a good component having a low ESR (<1 Ohm) is indicated. A Red LED indicates a High ESR condition (>10 Ohms), and a Blue LED indicates a Suspect component.

With this unit, there is no need to interpret a lookup chart (Capacitance vs Working Voltage), or a component datasheet.


































Specifications

•  Measures Capacitor ESR, then classifies the result into one of three test categories.
Microprocessor controlled. Provides precise, and repeatable digital measurements. 
•  Tests 1uF Capacitors, and above.  
Low ESR defined as having an AC resistance of 1 Ohm, or less.

Functional Test Procedure

  Install a 9 Volt Battery (not included), and attach the Test Leads.
  Ensure that the component to be tested is not connected to any Electrical circuit.       
    If so, safely remove the device from the circuit.
  Press the RED Test Button. The Test Result LED will turn Blue confirming an initial unknown state.
  Connect the Yellow Test Leads to the Capacitor-Under-Test. The leads can be connected in any random fashion.

Tips for First Time use

         •           Always use an Alkaline Battery (Energiser or Duracell). Nicads have a lower terminal voltage    (typically 7.2V) which can reduce performance when testing high current Hockey Puck devices.
       •            Be sure of the Specifications of your SCR before testing. Check the Manufacturers Datasheet if                     you are unsure. Testing a High Current SCR with a current rating above 150  Amps will cause                         the Test Result LED to stay Blue. A Blue Test Result LED indicates an unknown condition.

ESR (Equivalent Series Resistance) is an unwanted characteristic of a Capacitor. It is the sum of the dielectric resistance, and lead/plate bonding resistance.

Unfortunately, thermal and physical stress, high voltage transients, ESD, and other factors can change a Capacitors ESR - over time. This change causes electronic circuit failures.
