DC Power Systems & Inverters


The NetSure 5100 Series, a compact -48 volt DC power solution which can provide +24 volt DC power when equipped with converters, features an advanced control unit, a high efficiency rectifier, converter, solar converter and multiple distribution options to meet the demands of many different applications. The system is available in two types; an integrated version and an external distribution version. The rack mountable 19″ wide integrated version (582137200) provides up to 150A at -48 VDC and up to (9) positions available (with expansion rectifier shelf) for 2000 watt high efficiency eSure rectifiers and a distribution panel consisting of either (36) GMT fuse positions, (4) load breakers and (12) GMT fuse positions or (2) load breakers, (2) battery breakers and (12) GMT fuse positions. Optional battery or load low voltage disconnect contactors are available.

The external distribution version (582137100) provides up to 600A at -48 VDC and up to (29) positions available (23″ version with five module shelves) for 2000 watt eSure rectifiers, 1500 watt -48V to +24V converters or 2000 watt solar converters, a single or dual row distribution cabinet, and hybrid and solar connectivity panels. The rack mountable 19″ or 23″ wide power system is available in a number of configurations and designed to work with a wide range of applications. The 23″ wide distribution cabinet supports up to (52) 1A to 300A circuit breakers or 1A to 100A TPS/TLS fuses. Options for battery disconnect breaker positions and dual voltage (-48V /+24V) breaker panels are available. Multiple LVD levels are supported in the dual row distribution configuration, allowing load prioritization in up to two steps.

Remote monitoring and control is supported by multiple web browsers including IE, Firefox, Chrome and Safari. Standard protocols include ModBus, SNMP V2 & V3. Encrypted security is provided by IPv6 and SNMPV3. Local access is provided through the controllers? keypad and TFT display. NetSure DC Power systems from Vertiv? offer extremely low failure rates, as well as low total cost of ownership. The 2000 watt eSure rectifier delivers peak system efficiency above 96%. Maximum value is achieved by an advanced energy optimization function known as ECO mode, enabling energy savings even at low loads.


NetSure 5100 Series DC power systems are designed for deployment in telecom access network applications requiring a reliable and high power density supply up to 600 A at -48 VDC or up to 400 A at +24 VDC (external distribution version). The high operating temperature (+65?C) in conjunction with high operational efficiency has a positive impact on climate system dimensioning in outdoor enclosure applications. This DC power system is designed for insertion into EQ zone 4 compliant relay racks and cabinets.
