General Test Instruments

Electronic test engineers use a variety of precision instruments for R&D, vendor verification, and production testing. ETPS can supply a number of general test instruments that can be used in stand alone mode or automated for high throughput testing.
Dedicated battery test systems with automatic charge and discharge modes with data logging are available. The standard 16 and 32 channel systems have range up to 5VDC ensuring they're suitability for a wide variety of cells. Expandable custom systems providing up to 400 channels can be specified with voltage and current ranges to suit.

Automatic power supply testers for single or multi-output PSU’s are provided. Up to 12 test functions including PARD, Efficiency and regulation can be set up and sequenced to your testing requirements.

A compact test unit for checking the trip point of earth leakage circuit breakers is offered. Precision current shunts and a range professional power meters able to handle up to 12kW are also available.

Did You Know...

  • For testing Lead acid, Ni-Cd, Ni-MH and Li-ion batteries a portable capacity checker is available.
  • Please remember check our adjustable AC & DC Sources for psu testing.

This range consists of 3 digitising power meters that are used to measure both AC & DC Loads. Each unit is built with front panel control and display and includes an IEEE 488.2 interface as standard.

A total of 6 automatic switching ranges provide a tight resolution and high accuracy of the voltage and current being measured. Digital integration is used to calculate the power factor and actual power being taken by the unit under test.

Applications include power supply, computer, lamp and ballast and monitor testing. The 4012A is particularly suitable for adapter no load measurement as its lowest current range is 0-125mA.

The GPIB interface makes this unit ideal for integration into automated test systems. The carrying handle and low weight of 4.5kgs also make this unit suitable for mobile users. Retractable legs provide a good viewing angle.

- More Info
The GT-3660B is an automatic power supply tester that can simultaneously load up to 6 PSU output channels. The unit is delivered complete with a simple to use windows software programme. This allows the user to program up to 12 different types of tests and set individual test parameters along with duration times.

Test routines can be transferred from the users PC to the non-voltaile memory of the GT-3660B. The memory will store up to 24 separate routines. Finished test reports can be printed out directly via the unit’s centronics interface meaning that the unit can be used as a stand alone tester.

For a permanent soft record the results can also be transferred to a pc. Serial number and model details can be entered. Test information can be exported to Excel and then manipulated to suit your company’s report format.

For high throughput testing an integrated twin testing fixture is optionally available and ideal for ATX Power Supplies. The Automatic PSU tester is also used for a wide range of other power supplies. The technician can use the molex connectors on the PSU tester’s front panel or modify the optional universal test fixture to suit the UUT’s particular connectors.

If the standard GT-3660B isn’t suitable please contact ETPS for a modified version to meet your particular voltage and current ranges.

- More Info
The GT-3610D is an automatic power supply tester available as 75W and 300W versions. The unit is delivered complete with a simple to use Windows software program. This allows the user to program up to 10 different types of tests and set individual test parameters along with duration times.

Test routines can be transferred from the users PC to the non-volatile memory of the GT-3610D. As many as 30 separate test routines can be stored. Finished test reports can be printed out directly via the units Centronics interface meaning that the unit can be used as a stand alone tester.

For a permanent soft record the results can also be transferred to a PC. Test information can be exported to Excel and then manipulated to suit your company’s report format. For high throughput testing an integrated twin testing fixture is optionally available.

Along with a programmable load the GT-3610D also incorporates an AC & DC Source. This enables over voltage protection testing and line regulation. Static analysis with output Voltage and PARD percentages can also be programmed.

The 7550 model has five precision ultra stable current shunts which range from 0.001Ω to 10Ω. The internal current meter measures from 1mA to 250A. The five selector switches, shunts, binding posts and the internal 4½ digit AC/DC current meter display the respective shunt current.

By adding an external DVM of 5½ digits or higher the resolution and current read back accuracy can be increased. This compact unit is built into a 19” x 2U x 325mm case. Retractable feet provide a good view angle when the 7550 is used on the desktop. If cabinet mounting is required a flange kit is optionally available.
