Ht Power Supply Ipc. Housed in robust metal case with durable powder coated finish, this HT power supply unit is designed for use with valves, Teltron demonstration valves, ionisation chamber dosimeter, DC amplifier, parallel plate capacitor, Millikan oil drop apparatus, etc. and any other apparatus requiring up to 300V DC at low current. Three outputs are available two smoothed DC outputs 0 to 30V and to 300V (at up to 60mA) and one 6V 2A AC output (for filament heating). The DC outputs are continuously variable and supplied from two pairs of 4mm sockets colour-coded red/black. The AC output is available from pair of 4mm sockets colour-coded white. Each DC output has separate control with the DC voltage indicated on the graduated scale. The DC outputs are available simultaneously and are fully floating i.e. neither output is internally referenced to earth potential. The maximum current which can be drawn from the DC outputs is limited electronically to 60mA. An illuminated on/off switch is mounted on the rear panel adjacent to fused appliance inlet. Electrical Supply 220-240V AC 50-60Hz. Mass 2.4kg. Dimensions (L W H): 179 190 85mm.
