Current Pulsers and Laser Diode Drivers (Pulsed Current)
-
These instruments generate current pulses whose amplitude is largely independent of the load voltage. This makes them ideal for pulsing device whose voltage may vary with time (for instance, the voltage drop of laser diodes may vary with temperature, or explosive squibs which change impedance during ignition). This voltage independence is a trade-off with speed. If faster rise times are required, consider using pulsed voltage instruments instead.

Primary Current Injection Sets
-
Protective devices such as relays, overload Coils, Circuit breakers and CTS etc. must be checked regularly to ensure that they are always ready to operate correctly, Routine current injection testing will quickly detect faulty or incorrectly adjusted protection circuits / devices & will be possible to prevent serious damage to the system. Primary injection kit is designed to operate on single phase 230/240 volts AC 50 HZ to develop smooth & continuous test current as for loading, calibrating, and testing of CTS, Bimetal Relays, Protection Relays etc. The test set gives high current output at low cost and with inherent safety. The primary current injection testing checks all parts of the protection system by injecting current down the cable / bus bars. The application of the primary current injection sets is to ascertain the current carrying capacity of any Conductor, insulator, connector or calibration of CTS / Bi-metallic relays etc.
