The E61 is a Constant Voltage/Constant Current, multi-output
power supply with digital metering. It features four adjustable regulated
DC outputs : 0 to 30V at 2A, ±3C to ±15V at 1A, 5V to 6V
at 5A. The 0 to 30V supply is, additionally, a supply with automatic crossover
when the load current exceeds the value established by the current limit
setting. An independent current control allows the current limit to be
set to any value within the current rating, enabling the supply to be
used as a constant current source of regulation better than 0.2% and with
compliance voltage up to 30V.
The ± 3V to ± 15V dual tracking supply features a tracking
inaccuracy of less than ± 1% and finds wide application in the
testing of linear circuits that require accurately set, equal and opposite
DC voltages. The 5V to 6V supply doubles as a logic supply and as a supply
for powering 6V battery operated equipment. All outputs are completely
protected against short circuit and overload conditions.
