Basic Unit
A company needs to monitor the power
supply voltage (120VAC), load current (50
amps) and frequency (60Hz) of an AC
motor.
Voltage: A Mini-Max 200 Volt AC meter is
installed in parallel with the power supply.
Current: A Mini-Max 5 Amp AC meter
is attached to a 50:5 amp Donut Current
Transformer. The meter must be scaled to
display 50.0 when 5 amps are applied. R9
and R12 are adjusted until the correct value
is displayed. The meter is connected to the
Donut, and the negative line is fed through
the donut.
Frequency: A Mini-Max 200Hz Frequency
meter is installed in parallel with the power
supply and motor. The wiring for the volt
meter can be split to the frequency meter
as long as the voltage will not exceed 750
volts AC.
Your Mini-Max Current Indicator can be configured by making an entry for each box.
Note: Models for DC current, process, DC voltage, AC TRMS voltage, AC frequency and tem-
perature are also available.
Note: Special scaling is available from the factory at the time of ordering

Donut Current Transformers enable the
Mini-Max to monitor AC current up to
1999 amps. The Donut (also known as
a “Toroid”) is placed around one of the
legs of the device being monitored, and
emits up to a 5 amp signal. The Mini-
Max can be scaled to accurately display
the current being monitored. Each Donut
comes with 2’ long secondary leads.
