The PABX-DBS unit is a robust and extremely reliable DC battery eliminator / battery charger which provides a smooth, regulated DC output despite large mains and load variations. The unit complies with Telcom’s regulations and produces less than 2mv Psophometric ripple (referred to 800Hz).

The unit is of the full wave thyristor regulator type and has the advantage of rugged simplicity and high reliability with low heat dissipation. Protection is provided electronic current limiting and fuses. And important feature of this is parallel operation. This means high current capability and parallel redundant reliability. A further feature in parallel operation, is that units may be removed or replaced on load.
