Coil Tester & Power Supply POB30AD

The POB30AD is a powerful and reliable coil tester and power supply device manufactured under DV Power brand. It is designed to be used as part of circuit breaker test and measurement equipment. This device is a versatile tool that can be used as a DC and AC power source unit for circuit breakers during commissioning and regular maintenance and testing. Its typical application covers scenarios when substation battery is not connected or available.

The Outputs Features 

There are four separate DC and AC coil outputs for opening and closing coils supply (10V – 300V DC or 10V – 250V AC; up to 15 A)
DC Motor output is capable of withstanding a starting current up to 30 A at voltage range 10 V – 300 V. With the use of this output, POB test equipment can also be used as a power source or temporary battery charger.

Power Supply 

The POB instrument is an advanced part of circuit breaker’s test and measurement equipment. It is used as a power source unit that can provide stable and adjustable output voltage and current, enabling an analysis of the coil and motor graphs recorded with circuit breaker analyzers from different vendors. This device has a significant advantage over substation batteries as it enables testing in under-voltage and over-voltage conditions, which is essential for maintaining the reliability and efficiency of circuit breakers.

Test and Measurement Equipment: Coil Tester 

The POB tester is also a highly efficient coil tester tool, which can be used for coils current value measurements and minimum trip voltage – test of the circuit breaker’s coil. The Coil Tester & Power Supply Unit POB is ideal tool for professionals in the field of testing and measurement equipment, it can be used in factories and laboratories, but also in high induction switchyards, power and industrial environments.

Design 

The POB series is designed to be user-friendly, with an intuitive interface that allows for easy operation, calibration, and maintenance. The device’s rugged construction is built to withstand harsh testing environments, making it a highly reliable tool that can withstand various forms of mechanical and electrical stressors. Besides this, it is lightweight and portable and have the best output power vs. weight ratio in the market.

Benefits of POB Series 

In summary, the POB30AD Coil Tester & Power Supply device is highly reliable test equipment that provides dual purpose for circuit breaker testing:

• It can be used as a stable power source for coils and spring-charging motors 
• It can be used as coils and auxiliary circuit analyzer 

The DC output voltage is filtered and has ripple less than 1% which enables analysis of the coil current graphs recorded with Circuit Breaker Analyzers, moreover it is compatible with Analyzers from different vendors.
The POB instruments have separate outputs for open and close coils, also it enables testing in under-voltage and over-voltage conditions when used as a supply unit for testing Middle Voltage and High Voltage switchgears and circuit breakers with Circuit Breaker Analyzers.
