Description
These power units contain a regulated DC power supply and constant current circuits which
supply constant current DC power to 12 sensor channels. The constant current sources can be
individually adjusted to provide from 2 to 20 mA of drive current per channel.
There is also provision for operation from ex24 VDC batteries or DC power packs for use
where AC power is not available.
The front panel has 12 red/green LED’s so that sensor condition can be determined at a glance.
On the rear panel there are 12 Sensor BNC jacks and 12 Output BNC jacks. In addition, there are
terminal block inputs that can be used in lieu of BNC’s.
A rotary selector switch (12 position) on the front panel allows the monitoring of the DC bias
voltage of each sensor. This is a very handy troubleshooting tool for system checks. Readout is
by a front panel mounted 3 digit seven segment display. Also connected to this rotary switch is
a front panel mounted BNC ‘Monitor’ jack which allows the user to look at the signal from the
sensor connected to the selected channel. In this way each channel’s signal may be inspected.
A three position power switch on the front panel selects AC power or Ext DC power with an ‘off’
position included. The rear panel has a set of twin banana jacks for connection to the external
DC power source. The rear panel also contains the fuse holder and the IEC power entry
connector.
