XPiQ Inc. (Holliston, MA), a worldwide manufacturer and supplier of ac-dc and dc-dc power supply products, announced its CRP1K5 bulk power system for distributed power architectures, battery charging and N+1 redundancy architectures in telecom systems, data networks, optical routers and mass storage systems.
The CRP1K5 chassis accepts up to three CPD1K5 or CFP1K5, 1.5 kW power units for -54 Vdc or +48 Vdc outputs, respectively. Maximum system power output is 4.5 kW, or 3 kW in N+1 mode. The chassis is 2.89 in or 1.6U tall. Internal O-ring diodes in each power unit facilitate hot-swap and redundancy. With highest-in-class efficiency, typically 91% at full load, the power supplies generate minimal heat and each individual unit has integral forced-air cooling to save system space. The power supplies have universal ac inputs with integral power-factor correction, and meet all major international safety and EMC specifications.
The CRP1K5 system achieves a power density of 8.55 W/in³. Output rails require no minimum load and feature ±5% line and load regulation with ripple and noise within ±1% peak-to-peak. Full power is delivered at up to +55 °C ambient with de-rating at 2.5%/°C from +55 °C to +70 °C. Control signals include remote on/off, current monitoring, ac OK, dc OK, missing module, load sharing over a single wire connection with ±10% accuracy, and both over-temperature and over-voltage indication and protection.
The overall rack size is 14.66 in x 17.64 in x 2.89 in and it is designed for 19 in rack-mounting applications. The unpopulated chassis weighs 4.0 kg, and fully loaded with three modules, weighs 13.6 kg. A rack with three modules costs $2,053 in 100-plus quantities.
