Product Description
WV905 Power Supply
The WV905 power supply can be used to operate most 24VDC instruments, including Action’s Ultra SlimPak II, Ultra SlimPak, and ActionI/Q models. The WV905 will operate on input voltages ranging from 85 to 265VAC or 120 to 300VDC. The 24VDC, 0.5A output has overcurrent shutdown with automatic restart and thermal shutdown. The input is proteccted by fuse, a thermistor for inrush current protection, and a varistor for over voltage.
The WV905 is the perfect power source for Ultra SlimPak II signal conditioners and alarm units. The integrated power jumping system makes short work of connecting power, eliminating the need to “daisychain” power wires.
