Product Details Supplier Info More products

TDK-Lambda has introduced 1kW embedded 1U-high single-output AC-DC power supplies for standalone and distributed power architecture applications requiring 24V, 32V and 48V bulk power.

Up to 20 per cent output voltage adjustment is possible, enabling the RFE1000 series to be used in a variety of customer-specific applications, including battery charging.

Operating from a universal input of 85VAC to 265VAC, typical applications for the RFE1000 supplies include communications, factory automation and radio-frequency amplifiers.

Efficiency of up to 89 per cent minimises heat dissipation.

The RFE1000-24 ,-32 and -48 power supplies can be used individually or up to eight units can be connected in parallel to form an N+1 redundant power system with optional OR’ing diodes.

Each power supply has variable-speed cooling fans and can operate in temperatures ranging from 0C to +70C.

The RFE has a power density of 10.5W/in3 with dimensions of 305 x 127 x 41mm.

AC input is via a terminal block and DC output is via M5 studs.

Auxiliary outputs are via a JST-type 12-way connector.

Over-voltage, over-current and over-temperature protection are standard features and, for system monitoring, there are opto-isolated signals for DC OK, AC fail and over-temperature warning with a rear-panel light-emitting-diode (LED) indicator for DC OK.

Remote on/off control and remote sense features also come as standard.

Other standard features include single-wire current sharing and an auxiliary 12V 0.25A output with a built-in OR’ing diode.

As well as being EN55022 and FCC compliant (achieving Class B conducted and radiated emission), the RFE1000 series meets UL/EN 60950-1 safety approvals and carries the CE mark.

Harmonic correction meets the EN61000-3-2 standard and the power supplies are backed by a two-year warranty.
