Description

The GRD40A designates a full family of 400W low profile military grade C.O.T.S power supplies. The board includes EMI filters, reverse polarity protection, inrush current limiter and input surge limiter in order to fully comply with usual mil input bus standard such as Mil-Std-1275, and Mil-Std-704. The internal limiter sustains input bus disturbances from 12 Vdc level given by MIL-STD1275 IES (initial engagement surge), to 100V dc surge level.

Several fixed output voltages from 3.3Vdc to 48Vdc are available. The outputs can be trimmed from 10% to 110% of nominal value. A share function allows connection of several boards in parallel to boost output power. The power supply can be operated with a baseplate temperature ranging from -40 to 85°C.

The GRD40A comes with 2 independent and isolated 200W output channels that can be connected in series, parallel or with a common line, and +/- outputs. The power connections are made through 4 mm studs, the monitoring signals are available on standard low power connectors.

With 180mm X 140mm X 28mm dimensions, the board can be ordered uncoated, coated, or with a metallic chassis hood. The GRD40A is particularly suitable for demanding projects in various fields of application like ground borne vehicle, or navy.

Plug and play, the GRD40A is intended to speed up design processes reducing time to market.
