Portable Relay Tester
-
The protective devices such as relays, overload coils, circuit breakers must be checked regularly to ensure that, they are always ready to operate correctly. If a fault occurs in the equipment, which they are protecting, routine relay testing will quickly detect the faulty, incorrectly adjusted protection circuit and will possibly prevent serious damage to plant or injury to personnel. Apart from checking the protective circuits correctly, it is usually necessary to measure its operating time. The micro controller based time interval meter is used for this purpose in all AJIT brand relay tester.

Multiple Channel Burn In Power Supply
MCPS
-
The most important features of this burn in power supply is its ability to hold a constant output for each channel even in the event that a unit under test on one channel may short and fail. Since each channel has it''s own transformer, no glitches or voltage spikes can get into any of the other channels. This image shows the results as the second channel from the left is shorted with a small wire and the circuit breaker pops out. Used for burn-in testing and other timed testing where power isolation is required. Very basic simple circuit, see schematic below. Cleans and frees up benchtops, burn in racks and work space clutter. Available in benchtop or rackmount.
