Completely safe and uninterruptible operation with double input of! The unit can be used as a DC input ATX power supply! Model NSP23754S NSP23754S Description Model name coding 1 Series name 4 DC input voltage (battery voltage)48v type 2 Output power 5 Standard NSP2 375 D 4 S 3 Dsub terminal V output type, NSP23754S, is on page B82. Features DC startup is available. Since DC input is independent from the GND terminal, the unit can be used in various environment. Simultaneous input of DC48V and AC85 to 264 is suitable for important systems that require high reliability. Also, the unit can be operated continuously with DC48V input only. Each of,,and inputs has a rated voltage control function. An external variable resistor is mounted. Dimensions are those of BabyAT. Since DC input terminal is isolated, one external battery (lead) operate multiple units jointly (longterm continuous operation is possible). The battery can be shared with NSP2254S.
