Coil Analyzers & Power Supplies
Coil analyzers and power supply units are portable and lightweight devices intended for use in harsh switchyard and industrial environments. The typical application is switchgear and circuit breaker testing when substation battery is not connected or available. An advantage over substation battery is enabled testing in under-voltage and over-voltage conditions. Furthermore, the stable voltage outputs with a very low ripple (<0,5%) enable an analysis of the coil and motor current graphs recorded with circuit breaker analyzers from different vendors.
SAT40AD, POB30AD, and POB40AD are unique devices in the market due to their dual purpose:
Power supply for coils and spring-charging motors
Testing circuit breaker’s coils, motor, and auxiliary circuit
All DV Power coil analyzers and power supply units have four separate outputs for opening and closing coils.
SAT40AD has two powerful motor outputs (AC and DC) which can withstand up to 40 A inrush current.
POB30AD and POB40AD have DC motor output rated up to 30 A and 40 A respectively. With the use of motor outputs, POB and SAT can also be used as a power source or a temporary battery charger.
SAT40A II series instruments can be controlled via PC. The DV-Win application software is used to control both SAT and CAT (Circuit Breaker Analyzers & Timers) devices at the same time, making a unique test system for switchgear and circuit breaker testing.

Coil Analyzers
SAT Series
-
The Coil Analyzers SAT30A and SAT40A are powerful, lightweight units ideal for testing of circuit breakers. Substation battery is not connected or available. The SAT series instruments are intended to supply circuit breaker coils and spring charging motors. They spring charging motors (SAT40A – AC and DC) as a part of commissioning and maintenance testing.

Coil Testers & Power Supplies
POB Series
-
Coil testers and power supply units, models POB30 and POB40 are ideal for commissioning and maintenance testing of circuit breakers. The station supply is not available. The POB series are power supply units implementing the latest power electronics technology. They are developed for use in switchyards, power and industrial environment. In addition to providing current and voltage for breaker testing, they can measure certain coil parameters.
