DMS-20PC-FM Series

Self-Powered, 3-Digit LED Display

AC Line Frequency Monitors

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.

FEATURES

Self-powered, no external supplies required

3 models:

47.0-99.0Hz (85-140Vac)

47.0-99.0Hz (170-264Vac)

350-450Hz (85-140Vac)

Screw terminals simplify panel mounting

Ideal for emergency power equipment

Small 1.38" x 0.88" x 1.0" packages

Epoxy encapsulated for harsh environments

Large (0.40"/10.2mm) red LED displays

An ultra-stable, quartz-crystal-con-

trolled, embedded microcomputer provides

accuracies of 0.1Hz (50/60Hz models) or

DMS-20PC-1-FM-F

(With blade terminals)

1.0Hz (400Hz model) over the entire oper-

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).
