SECTION 3 - OPERATION
3.1
INTRODUCTION
BOP BIPOLAR OPERATIONAL POWER SUPPLIES can be used in a great variety of applica-
tions. As a PRECISION VOLTAGE or CURRENT SOURCE, the BOP output can be controlled
locally (by means of the front panel BIPOLAR voltage and current controls) or remotely (by
means of resistances or by voltage signals). Independently adjustable (or remotely programma-
ble) limit circuits for both output voltage and output current protect a sensitive load from any
overvoltage or overcurrent. As a BIPOLAR AMPLIFIER, the BOP output responds to such input
signals as sine, square or triangular waves. A (±) 10 volt input signal will program the BOP out-
put (voltage or current) through its rated output ranges. Built-in preamplifiers, for the voltage, as
well as the current channel of the BOP, permit amplification of the control signals to the required
amplitude and the interface with high as well as low impedance signal sources.
Detailed examples of the more popular applications are described in the following paragraphs.
Before actual operation, however, the following general comments on the operation of the BOP
should be carefully considered:
1)
THIS EQUIPMENT IS CAPABLE OF PRODUCING LETHAL VOLTAGES. Exercise
extreme care in making all connections to and from the BOP terminals. REMOVE A-C
POWER FROM THE BOP BEFORE MAKING ANY CONNECTIONS!
2)
An interlock device removes the A-C source power from the BOP if the rear terminal
cover plate if lifted. DO NOT BYPASS THE INTERLOCK.
3)
Wires and/or cables, connected from the BOP terminals to external components or
programming devices must be properly insulated and securely terminated on both
sides to avoid accidental contact. A feed-through hole is provided on the BOP rear ter-
minal cover, to bring the wires from the BOP rear terminals to the outside. DO NOT
USE BANANA PLUGS WITH EXPOSED SCREWS OR OTHER EXPOSED METAL
PARTS AT THE FRONT PANEL OUTPUT TERMINALS!
4)
The BOP chassis and cover must be safety-grounded to a reliable a-c source ground.
A safety ground may be established by using a grounded a-c power outlet or, if the lat-
ter is not available, by means of a separate wire, from a provided “ground” terminal to a
reliable a-c source ground point.
5)
THE COMMON OUTPUT TERMINAL OF THE BOP SHOULD BE SIGNAL
GROUNDED. If for any reason, grounding of the output is not possible, additional pre-
cautions must be taken to make any access to the isolated output impossible.
6)
FOR ALL CONTROL ADJUSTMENTS ON THE BOP, USE ONLY THE INSULATED
TOOL WHICH IS ATTACHED AT THE REAR. (See Section 2, FIG. 2-2).
