7400-DS93 1RU DC Breaker and Fuse Panels The 7400-DS93 Breaker Interface Panel offers a reliable solution for protecting your system from over-current damage. 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 90 Amps per side. The unit is designed with a removeable front panel to provide access to 6 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-DS93 Input and Output Voltage Operating -48VDC nominal (Reverse Polarity Protected) Voltage Range -36VDC to -72VDC Current Rating 90 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 1.725”H x 12.00”D Temperature Range 0 - 50°C (32 - 122°F) (Without Forced Air Cooling) Temperature Range 0 - 65°C (32 - 149°F) (Without Forced Air Cooling) Operating Humidity 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. 0 - 95% Operating Elevation 0 - 10,000 ft (0 - 3000 m) Weight ≈ 12 lb (≈ 5.45 kg) Rev: 04/01/2014 +1 888.588.3448 [email protected] power.apitech.com www.apitech.com
