Helios Rectifier 25/48 Installation and User Manual
Helios Rectifier 25/48     NT5C06D(X) –48 V / 25 A Switch Mode Rectifier
The NT5C06D provides -48 V / 25 A of isolated, filtered, and regulated DC
power from a single phase AC source, for powering a load while charging a
positive grounded battery. The output voltage can be adjusted from 46.0 to
56.0 V for floating a 23 or 24 cell battery string.
The rectifier is designed for automatic precharge upon insertion into the
MPS75 power shelf. When the NT5C06D is plugged into a power shelf with
battery back-up, or with other rectifiers running, the DC circuit breaker must
be in the OPEN position (OFF position).
Each rectifier plugs into the MPS75 power shelf and does not require any
other connections. The rectifier is equipped with a 13 A, two-pole, AC input
circuit breaker; a 35 A, single-pole, DC output circuit breaker; a digital
ammeter; and a set of LEDs, switches and potentiometers for threshold
adjustments and alarm indication. The rectifier uses high frequency switching
technology, is cooled by forced air, and can be equipped with an optional air
filter.
