Power Supplies
These power supplies have been designed especially for checking bonding 
and grounding of electrical equipment, as mandated by CSA Standard C2.2, 
No. 0.4, and equivalent documents from UL and other standardizing agencies. 
The various models can provide a range of current up to 500 A, with voltage 
compliance up to 30 V, higher if required for special tests. Separate
voltmeter terminals are provided to enable a four-terminal resistance
measurement.  Many other combinations of voltage and current are available.

Constant-Current AC

These Constant-Current AC Power Supplies are used primarily for heat runs on 
cables and connectors in accordance with CSA and UL standards. ON and OFF 
times may be set independently. A counter shows the total number of ON-OFF 
cycles of operation in a given test run. 
The output current is regulated and many be set at any desired value from near 
zero up the maximum rating of the test set. A three-position switch selects the two 
mode of operation - continuous or timed - plus an OFF position. A ''zero-start'' 
feature ensures that full current is never applied instantaneously. The current 
always starts at zero and increases to the set value (generally in a few seconds).

REGULATED DC POWER SUPPLY

  • Three output ranges
  • Well regulated
  • Linear regulator - very low EMI
  • Low ripple
  • Short-circuit proof
  • Reverse-voltage protection
  • Remote sensing
  • Bench mount
  • Made in Canada

MODEL
VR-50/100/200-6/3/0.6L-AV

SPECIFICATIONS

INPUT VOLTAGE

120V, 60 Hz, single phase, approx. 5 A

OUTPUT VOLTAGE

0-50/100/200 V dc, continuously adjustable
(3 ranges

OUTPUT CURRENT

6 A max on 0-50 range
3 A max on 0-100 V range
0.6 A max on 0-200 V range
Current limit is adjustable up to about 5% more than max rating by a front-panel control.

LINE REGULATION

If the input line voltage changes +/-10% from its nominal 120 V, the output voltage will change no more than +/-0.03% or 15 mV, whichever is greater (at any load current within rating).

LOAD REGULATION

For changes in load current from 0 to rated maximum, the output voltage will change no more than 0.15% or 50 mV, whichever is greater (at any line voltage within rating).

In the current-limiting mode, the current regulation is approx. +/-1% over the available voltage range.

RIPPLE AND NOISE

The rms value of the ripple and noise voltage will be no greater than 0.05% or 10 mV, whichever is greater (at any line voltage or load current within rating).

INPUT PROTECTION

Circuit breaker

OUTPUT PROTECTION

Output may be shorted continuously without damage to the unit. Power supply recovers automatically to normal when short is removed.

METERS

Standard on all units

REVERSE-VOLTAGE PROTECTION

Provided by a reverse-biased diode across the output

OUTPUT TERMINALS

''5-way'' binding posts on front panel (with safety cover)

OUTPUT FLOATING

Either side may be grounded or connected to any other voltage as long as the peak voltage from either side to ground (chassis) does not exceed 1000 V.

SERIES OPERATION

Permitted, subject to the above voltage restriction

OPERATING TEMP. RANGE

0C to +40C (full load)

EMI (RFI)

EMI radiation and susceptibility are essentially zero for all units.
