XP Power is releasing its new GCU500 series of 500 W AC-DC power supplies with leading features including a size of just 83,8 x 165,1 x 39,3 mm. Conveniently fitting into 1U systems, these rugged products are ideal for high-reliability but cost-sensitive industrial applications such as robotics and renewable energy.
Dual fusing, low leakage current and input/output isolation of 2 x MOPP (Means Of Patient Protection) allow use in critical medical applications such as ventilators and medical carts in hospital environments. The products meet the latest ‘third edition’ of medical standard IEC 60601-1 including risk management. Unlike many competing products, the GCU500 series is rated for safety at high altitudes – 4000 m for medical and 5000 m for IT.
Latest resonant conversion and synchronous rectification techniques result in very high efficiency, up to 93%, giving low running cost, reduced operating temperature, extended lifetime and energy savings. Mechanical form factor is a U-channel weighing just 748 grams maximum with screw terminal connections for the main output. Input connections are Molex type or screw terminals when the optional fan is fitted.
Operating temperature range is -40°C to +70°C with full power available up to +50°C. The input voltage range is 80 to 264 V a.c. with full output power maintained down to 90 V a.c. and just a 20% reduction at 80 V a.c. A useful 250 W is available without fan cooling. The products provide a single main output of 12, 15, 18, 24, 36 or 48 V d.c. with convenient 5 V standby and 12 V fan supplies, and feature remote on/off and power fail signalling as standard.
The latest EMC standards are met for both industrial and medical applications, including the stringent class B level for conducted emissions to EN55011/32, and medical 4th edition. Internal protection features include over-voltage for the main output with short circuit and overload for all outputs and an overall over-temperature limit.
