MPSU 200

The new MPSU 200 has a small and flexible design which makes it the ideal choice for applications where an expandable, easy serviced and reliable power supply is required to fit into minimal available space. The MPSU 200 is a 3U high, 19″ wide and 240mm deep Modular Power Supply Unit, capable of delivering up to 1600W of output power. Distribution modules of different sizes can be plugged into the system at any time, easing system expansion and lowering start-up costs. Rectifiers, alarm module and distribution capable of up to 1600W can be fitted into a single unit. The MPSU 200 has parallel connection with the SMPS 200 rectifier modules.

The MPSU 200 can accommodate up to 8 rectifiers, if no internal distribution is required. The distribution unit comes in two sizes, with different amounts of load and battery MCB`s and an optional Low Voltage Disconnect. The AL 175 NT is used for system control and monitoring and provides local and remote supervision via voltage free contacts, modem or SNMP.


High Current G-Series

The G-Series® High Current Power System (HGS) is a multi-cabinet high capacity –48 VDC bulk power system with an output DC current rating of up to 10,000 Amps. The HGS is based upon the G-Series® digitally controlled 70 Amps rectifier module. This advanced rectifier design offers high efficiency, high power density, a high power factor, and it has low thermal and electromagnetic emissions.

The HGS is a modular design with various charge bay and distribution bay configurations available. Each charge bay is configured as six shelves of four 70 Amp rectifiers, for a total of 24 rectifiers per bay. Load and Battery Distribution /Termination bays are configured with large capacity fuses for branch distribution to external distribution cabinets.

The HGS is a bulk power system designed for Internet Service Provider, Colocation, and Central Office installations with large amounts of DC powered telecommunications equipment drawing heavy current. Each charge bay delivers 1680 Amps DC output. A typical 5000 Amps system consists of three charge bays, one battery distribution fuse bay (BDFB), and one Load Distribution Fuse Bay (LDFB). All equipment is designed to operate in a temperature range of 0 °C to +50 °C (32 °F to 122 °F). Various AC feed options are available to suit nearly any AC power infrastructure.
