Communication sites require isolated DC Converters to provide excellent voltage regulation, low noise, and high efficiency voltage conversion. Reliability is vital under continuous duty operation and high ambient temperatures. All these aspects were incorporated in the design of our rack-mount DC Converters.

These units accept a wide input range at 24 or 48VDC nominal, positive or negative ground, and produce pure 12 or 24 volt power. The solid state circuitry is conservatively designed and semi-conductors are selected and tested to withstand 200% of normal operating power.

Output voltage is maintained within 1% for all line and load conditions and the output is well filtered, allowing use with sensitive transceivers and telecom equipment.

Features
48, 24 volt inputs; 12, 24 volt outputs; positive, negative or floating ground.
Input/Output chassis isolation 250VDC
400 watt output
Rated for continuous duty at full load.
Excellent regulation under all line/load conditions.
Low ripple provides noise free output.
High efficiency 87% typical.
Easily adapts to both 19" and 23" racks, centre mount (6" from front)
Output volt and ammeter
Output voltage adjustment on front panel
Low profile occupies two RU (one RU space above and below recommended for cooling)
