Small power supplies have high peak load capability

23 March 2005 Power Electronics / Power Management

Many industrial applications produce high peak loads of very short duration, particularly at start-up. This means that system designers often have to over-specify power supplies for such systems with attendant increases in size and cost, both of which are directly proportional to output power. The SMC500/600 series of compact 500/600 W AC/DC switchers from XP eliminates the problem by delivering up to 80% higher power than their nominal rating for up to 500 μs. This means peak loads can be handled by a smaller, less expensive power supply than would otherwise be necessary. In addition, efficiency is maximised and wasted heat minimised because a power supply's highest efficiency is attained when it operates close to its full rated load.

The SMC500/600 single-output power supplies have universal AC inputs (90-264 V a.c.) with active power factor correction and output voltages from 3,3-54 V d.c., adjustable by ±5%. Where more than 600 W is needed, one version can deliver 800 W with high line (180-246 V a.c.) input or integral O-ring diodes are an option that can be used to facilitate current sharing.

All models come in a 233 x 108 x 63,5 mm housing and are complete with cover and fan for easy mechanical and electrical installation. They do not need external cooling arrangements. Efficiency is at least 80% with 230 V a.c. input for outputs above 5 V and 70% minimum for 5 V and 3,3 V output versions.

Comprehensive control and protection features include remote on/off, remote sense, over-voltage and under-voltage protection, overload protection and over-temperature protection. The power supplies meet international safety agency approvals and EMC standards.
