Description
| Simpson’s Percent Motor Load panel
meters, housed in century style case, are available in 3-1/2"
and 4-1/2" sizes. An attractive design with phenolic case and
glass windows, the century style provides visual monitoring of load
conditions of AC & DC motors while running. This monitoring
can prevent overloading and motor burn-out and establish and maintain
optimum operating load conditions. Scales show percent load from
0 to 150%. Scale is green from 0 to 100%, yellow from 100 to 125%,
and red from 125 to 150%. AC Load meters can be used with all AC
motors of any horsepower, voltage, frequency or phase. DC load meters
require an external shunt and potentiometers while AC load meters
require an external current transformer. Simpson’s external
shunts and transformers are sold separately. All AC meters have
iron-vane movements that are magnetically damped and can be used
for non-sinusoidal wave forms. DC units have annular movements that
are stable even under the most severe shock and vibration conditions. |
