175W and 350W supplies for CompactPCI 19in racks
Schroff, one of the industry's leading manufacturers of CompactPCI Microcomputer Packaging solutions, has unveiled a complementary range of 19" power supplies.
Cut-down prices for CPCI
Europac Integral offers all the benefits of a standard CPCI system including high stability, robustness and EMC shielding but at a far-reduced cost.
Able to accept inputs ranging between 20 and 72V, the new power supplies represent the ideal solution for industrial and telecommunications applications.
The CPDC units, which are only 6HP wide, deliver an output power of 100W across all input and output voltage ranges, including integral redundancy diodes.
Models providing between one and three output voltages are available, with 5, 12, 15 and 24V as standard.
Schroff development engineers have employed V/I-characteristic current limiting to ensure trouble free operation of every type of load, including motors and battery chargers.
Thanks to the high overall efficiency of between 85 and 90%, the convertors dissipate significantly less power than earlier device generations, and hence generate far less heat.
The single version with one output employs active isolation for redundancy operation.
In the dual units, the two output voltages can be adjusted to give a symmetrical output of between 11.5 and 15.5V.
The triple module delivers a power of 50W at the main output; the user being able to take 25W from each of the secondary outputs, which are isolated from the main output.
Single version units in the CPDC series allow current sharing operation and provide overcurrent protection at the input plus external "active off" control (TTL).
On the input side the undervoltage protection switches at 19V, and overvoltage protection at 73V.
The input circuit allows a soft-start with overcurrent limiting.
