Current Supply Units CSU 600A / 600AT

These high-current supply units have two main fields of application. The first is to conduct primary tests on protective relays. A primary test shows whether all parts of the protection system are functioning together properly within the specified time limits under operating conditions.
The second field of application involves conducting maximum current tests on low- and high-voltage circuit breakers, as well as overcurrent devices.

The CSU 600A is a compact instrument which, together with Timer TM200 and an external ammeter, meets stringent requirements for accuracy, easy handling and performance. This current supply unit is ideal for a) performance and turn-ratio tests of current transformers, b) primary tests of protective relays, c) maximum current tests on low- and high-voltage circuit breakers and d) commissioning tests that require variable currents.

The more sophisticated CSU 600AT provides a more comprehensive solution. It has a built-in timer and an analog ammeter that provide rough current settings quickly and easily. As a result, connection time has been reduced to the bare minimum.

The CSU 600A and 600AT current supply units have the best weight/performance ratio on the market. A convenient cable set and transport case are available.

For applications requiring higher currents, we recommend Programma's ODEN Primary Current Injection Test Systems.
