The Solid State Power Control Module(SSPCM) delivers 120 volts DC [Direct Current] from the Station to the racks and converts it to 28 volts DC, and delivers that power to a three-outlet power strip for use by the payloads. The SSPCM sends 120 volts DC to the RIC [Rack Interface Controller], the AAA [Avionics Air Assembly], and the PEHB [Payload Ethernet Hub/Bridge]. The SSPCM also provides data interfaces for payloads, including analog(two for each middeck locker and one for each ISIS [International Subrack Interface Standard] drawer) and bidirectional discrete(three for each middeck locker and two for each ISIS drawer). 2, record 1, English, - solid%20state%20power%20control%20module

In designing ISS [International Space Station] to accommodate sub-rack payloads it became apparent that several advantages would be obtained if investigators building MLE-based [equipment [Mid-Deck Locker Equivalent - based] were provided with host racks with a standardized set of interfaces. Based on this the EXPRESS rack concept was born. EXPRESS stands for Expedite the PRocessing of Experiments to the Space Station. The purpose of the EXPRESS rack is to allow quick ... and simple integration of payloads into the ISS. The EXPRESS Rack contains standard interfaces within an ISPR [International Standard Payload Rack] configuration to allow payloads quick and standard access to ISS resources. The EXPRESS Rack offers structural support hardware, power conversion and distribution equipment, data and video equipment, nitrogen and vacuum exhaust distribution hardware, and thermal support equipment. 3, record 3, English, - EXPRESS%20rack
