Emerson NT5C06D Applications, Equipment Identification, MPS75 NT5C10CX  power shelf 23-inch

12 Introduction

Applications

The rectifier is designed to function as the prime source of power for equipment requiring -48 V DC. It will also operate as a battery charger or as a battery replacement (batteryless operation). Its low output noise and good voltage regulation, combined with a 0.01% V coefficient for each degree C of temperature, provides an excellent charging facility to maintain a battery fully charged.

The NT5C06D rectifier is designed to operate continuously in a small or large power system. The NT5C06D is compatible with all other Astec rectifiers, and can be interfaced with other commercially available standard (compatible) rectifiers and power plants. The NT5C06DA/DB is designed to operate in temperatures ranging from 0°C to 65°C.

Equipment Identification

The MPS75 is a power shelf that can support up to three NT5C06 rectifiers. The rectifiers plug into the shelf, which provides interconnection points for AC input, DC output, and alarm and control signals. Each power shelf requires either three AC feeds (one for each rectifier) for the individual AC models, or a single AC feed for the three shelf rectifiers for the common AC models. Its output connects to the charge busbar or to the load distribution

panel through two cablesbattery and battery return. Each rectifier position has its own connector-terminated alarm and control cable going to the power plant control and monitor unit.
