The U-chassis design DDP1200-UCF forced-air cooled AC/DC power supply is currently available in a 24 VDC standard output voltage version. The series is well suited for challenging system designs where low profile and low power dissipation are desired with minimal air flow. The forced-air cooled UCF version provides a 12V auxiliary output, thus eliminating the need for an additional fan supply. The series delivers a steady 1000 W over the full input voltage range of 85 – 305 VAC, or a steady 1200 W from 180 VAC and above input line voltage.
The DDP1200 series 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. 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 60950-1 and 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.
