Series Description

The UWQ series offers high output current (up to 17 Amps) in an industry standard “quarter brick” package requiring no heat sink for most applications. The UWQ series delivers fi xed DC output voltages up to 204 Watts (12V @17A) for printed circuit board mounting. Wide range inputs of 18 to 75 Volts DC (48 Volts nominal) are ideal for datacom and telecom systems.

Advanced automated surface mount assembly and planar magnetics deliver galvanic isolation rated at 2250 Vdc for basic insulation. To power digital systems, the outputs offer fast settling to current steps and tolerance of higher capacitive loads. Excellent ripple and noise specifi cations assure compatibility to CPU’s, ASIC’s, programmable logic and FPGA’s. No minimum load is required. For systems needing controlled startup/shutdown,  an external remote On/Off control may use either positive or negative logic.

A wealth of self-protection features include input undervoltage lockout and overtemperature shutdown using an on-board temperature sensor; overcurrent protection using the “hiccup” autorestart technique, provides indefi nite short-circuit protection, along with output OVP. The synchronous rectifi er topology offers high effi ciency for minimal heat generation and “no heat sink” operation. The UWQ series is certifi ed to safety standards UL/ EN/IEC/CSA 60950-1, 2nd edition. It meets RFI/ EMI conducted/radiated emission compliance to EN55022, CISPR22 with an external fi lter.
