This high power current source module has been designed for precision constant current source applications requiring high impedance over a wide bandwidth. Typical applications include valve anode loads, single ended Class A amplifier loads, high impedance power feeds for high power shunt regulators.
As long as the terminal polarity of the CCS1 is respected it can be treated as a two terminal current source for use on positive or negative supply rails. In this case the anode (positive terminal) goes to the more positive potential.
All CCS1A modules can be used at dissipation ratings of up to 50 watts continuous (100 watts peak when used with the Z100A shunt regulator during power-up). The modules feature a heavy-duty, copper mounting bracket, which must be correctly mounted on a suitable heatsink for efficient thermal transfer. Contact me for advice regarding heatsinks as regulator dissipation and heatsink size can be optimised to match your project. For dissipations of under 5 watts no additional heatsink is required.
CCS1A-200 15 to 200 volts, 10 ma to 5 amps, max dissipation 50 watts
CCS1A-550 15 to 550 volts, 10 ma to 250 ma, max dissipation 50 watts
