7400-DS79 2RU DC Breaker and Fuse Panels API Technologies’ 7400-D-79 Breaker Interface Panel offers a reliable solution for power distribution and circuit protection. Power and return lines for all panel circuits are isolated in the “off” state by magnetic circuit protectors, offering superior protection and safety. This panel operates at -48VDC with a maximum current of 70 Amps per side. The unit is designed with a removeable front panel to provide access to 12 pluggable circuit breakers. A bi-color LED over each input terminal block provides verification of proper polarity termination at power hook-up. Red indicates a reverse polarity condition. Technical Specifications: P/N 7400-DS79 Input and Output Voltage Operating -48VDC nominal Voltage Range -36VDC to -72VDC Current Rating 70 Amps per Side Max. Lug Size Panduit #LCD4-14AH-L For #4AWG External Power Feed Wiring to PDU Power Output -48VDC PE Ground Panduit #PV6-10R-E For #6AWG External Ground Wire or Braid to the PDU Physical and Environmental Size 17.0”W x 3.470”H x 12.06”D Temperature Range 0°C to 50°C (32°F to 122°F) Temperature Range 0°C to 65°C (32°F to 149°F) Operating Humidity 0 - 95% Operating Elevation 0 - 10,000 ft (0 - 3000 m) Weight ≈ 25 lb (≈ 11.34 kg) Features: -- Circuit breaker protection for your valuable DC system. -- Power and return lines are isolated for all circuits in the “off” state by magnetic circuit protectors. -- A bi-color LED over each input terminal block assures correct polarity during hook up. Red indicates reverse polarity. -- Positive polarized latching connector system provides for quick field installation. -- With the removal of the front access panel, the individual circuit breakers can easily be serviced to minimize down time. -- PDU circuit protection configuration is easily modified by the user but not to exceed the maximum current rating of the PDU per output. -- PDU circuitry utilizes bus bar and PCB “Heavy Trace” technology for enhanced power dissipation.
