The series delivers 600 W of output power up to 137 VAC, or a steady 750 W from 180 VAC and above input line voltage. The DDP1200 power supplies are parallelable for redundant and/or higher power applications, facilitated by the internal OR-ing and current sharing functions.
The series offers both analog and digital controls. Analog signals include DC Power-OK, PS-Inhibit, voltage adjustment, remote sense and current share controls. The digital control uses the standard PMBus™ protocol which allows communications and data logging between the power supply and system, and includes monitoring of input voltage, output voltages (+V1), output current (on +V1), current sharing, thermal health, fan health, life hours, power supply and status information information. Additional alarm signals include fan fault, protections failure (OV, OC, OT) and voltages out of specifications. An LED visually indicates power supply status.
The DDP1200 series complies with the latest UL/IEC/EN 62368-1 standards for Audio/Video and Information Technology equipment and UL 8750 standards for LED lighting
applications. It also complies with the Class B standards EN 55011, EN 55032 and FCC for conducted and radiated emissions, IEC/EN 61000-3 Class A for harmonic content, and EN 55024 for EMC immunity.
