DATEL's new DMS-20PC-FM Series are the world’s smallest, self-powered, ac fre-
quency meters. Simply connect the ac line to the two rear input terminals, and the unit is
fully operational with no additional components or auxiliary power required! Two, 50/60Hz
models operate over input voltage ranges of 85-140Vac or 170-264Vac. A third, 400Hz
model operates over an input voltage range of 85-140Vac. Despite their small size (1.38"
x 0.88" x 1.0"), DMS-20PC-FM meters feature large 0.40"/10.2mm red LED's that can be
easily read from 15 feet away.
An ultra-stable, quartz-crystal-con-
trolled, embedded microcomputer provides
accuracies of ±0.1Hz (50/60Hz models) or
±1.0Hz (400Hz model) over the entire oper-
DMS-20PC-1-FM-F
(With blade terminals)
ating temperature range of –25 to +60°C.
Epoxy encapsulated plastic packages
provide excellent protection against the
harsh environments normally encountered
DMS-20PC-1-FM
(Panel mount)
by emergency backup power generators.
DMS-20PC-FM meters are the exact same
size as DATEL's popular AC Line Voltage
Monitors (models DMS-20PC-X-LM).
