Unipower PowerCassette PCM/TPCM Series Front-End Switchers - 1U High, Up to 800 Watts with PFC and Integral Hot Swap Provision Simple Type: Power Supply

The PowerCassette is an advanced-design, front-end switching power supply that employs a unique, new architecture which permits quick factory programming of its output. There is a high current output and a 5VDC ¼ ampere independent standby output. Maximum continuous output power is 650, 700 or 800 watts, with available voltages of 12, 24 or 48VDC, respectively. The PowerCassette front-end is ultra-compact, only 1.6 inches high, 5 inches wide and 10 inches deep, producing up to 10 watts per cubic inch power density. The unit comes in two versions: the PCM model which is the standard, non-hot-swap version; and the TPCM model, which is the hot-swap version with a handle and mounting bracket with jackscrews. See Figure 1. There is also an IEC AC input connector with switch option and a reverse air flow option. Both of these have reduced output capability. PowerCassette incorporates control and monitoring features including enable and inhibit inputs, AC power fail and DC power good signals, over temperature warning and remote sensing. The front panel has two LED status indicators: one for AC Power Fail and the other for DC Power Good. The output has a single-wire, current sharing capability. Two 19-inch, 1U-high racks are available to hold two or three PowerCassette units connected in parallel to give up to 800 watts with 1+1 redundancy or 1600 watts with non-redundant operation for the two-unit rack or up to 1600 watts with 2+1 redundancy or 2400 watts with non-redundant operation for the three-unit rack. The racks feature IEC60320 AC input connections.
