NetSure™ 721 Power System

The modular NetSure™ 721 power system with 3500 watt or 2000 watt high efficiency rectifiers and 1500 watt DC to DC converters provides up to 4000 amps of current for –48 volt systems with up to 930 amps at +24 volts. The basic components of the power system include the ACU+ control unit, module mounting shelf assemblies which house the rectifiers and converters, and a modular distribution cabinet.

The NetSure™ 721 power system contains a powerful, microprocessor-based control system capable of monitoring and controlling up to 60 rectifiers and converters. The ACU+ controller provides a 4×16-character alphanumeric display, which can be activated at the touch of a keypad.

The NetSure™ 721 can be expanded to up to three distribution bays for a total capacity of 4000 amps and up to twelve distribution panels. Each NetSure™ 721 distribution cabinet is modular by row and position. Four distinct distribution cabinet sizes are available to accommodate from one to four distribution panels. This allows the system to be configured in relay racks of various heights for installation in low-profile sites or atop batteries or other equipment to make more effective use of floor space. Several distribution panels are available offering different combinations of distribution positions, low voltage disconnect and battery disconnect options.

Distribution device options include 1 amp to 250 amp bullet-style circuit breakers, 3 amp to 125 amp TPS-style fuses in plug-in bullet-style holders, 100 amp to 800 amp GJ/218-style circuit breakers, 70 amp to 250 amp TPL-B style fuses and 70 amp to 800 amp TPH-style fuses. These devices can be configured for both –48 V load and battery disconnect and +24 V load (bullet devices only). A GMT fuse module is also available.

Features:

  • High Efficiency – 96.5% efficient eSure™ rectifiers ensure optimized total cost of ownership
    Modular Design – simple to install and operate; allows incremental cost-effective system growth
    Advanced Controller – offers battery management, AC service monitoring, site monitoring and configuration management
    Remote Access – options allow users to view, control and interact with the system using an Ethernet interface
    Plug’n’Play – add rectifiers and converters without changing the settings and making adjustments; no system interruption
    Front Accessible – allows for easy installation, additions and maintenance
    Constant Power – delivers more current at lower voltages to meet load or recharge demand
    Safety Compliance – NEBS Level 3 certified; UL Listed to UL subject 1801
