DV Power Coil Analyzer SAT40A
Coil Analyzer SAT40A is a powerful instrument ideal for testing of circuit breakers, where substation battery is not connected or available. The SAT40A is intended to operate breaker coils, and spring charging motors as a part of commissioning and maintenance testing.
SAT30A measures current and resistance of circuit breaker coils. SAT40A can also be used to test minimum trip voltage of circuit breaker coils, as well as under voltage releases of circuit breaker. Output voltage is selectable from 10 V to 300 V DC or from 10 V to 250 V AC.
The set is equipped with thermal and over current protection. SAT40A is easy to use and has accessory cable-set with touch-proof contacts.
The SAT40A has very high ability to cancel electrostatic and electromagnetic interference in the HV electric fields. It is achieved by very efficient filtration. The filtration is made utilizing proprietary hardware and software.
DV POWER Coil Tester & Power Supply POB40AD
- Circuit breaker coil operation
- Spring-charging motor supply
- Lightweight – only 10 kg
- Minimum trip voltage test of the circuit breaker’s coils
- As a power supply for tests with breaker analyzers from different vendors
Coil Tester & Power Supply POB40AD is powerful, lightweight power supply device, ideal for operating and testing circuit breakers coils. It is also intended to supply spring-charging motors with the possibility to generate the inrush current of up to 40 A. For supplying the circuit breaker auxiliary circuits, it provides wide output DC (10 – 300 V) and AC (10 – 250 V) voltage ranges.
POB40AD has built-in capability to perform an automatic test of minimum trip-voltage (in accordance to IEC 62271-100 and ANSI C37.09 standards).
POB40AD can be used as a general power supply device or a temporary battery charger. Note that it is compatible with the circuit breaker analyzers from different vendors.
