Self-Powered, 3-Digit, LED AC Line Frequency Monitors
DATEL's new DMS-20PC-FM Series are the world's smallest, self-powered, ac frequency 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-controlled, embedded microcomputer proDMS-20PC-1-FM-F (With blade terminals) vides accuracies of ±0.1Hz (50/60Hz models) or ±1.0Hz (400Hz model) over the entire operating temperature range of 25 to +60°C. Epoxy encapsulated DMS-20PC-1-FM plastic packages provide excellent (Panel mount) protection against the harsh environments normally encountered by emergency backup power generators. DMS20PC-FM meters are the exact same size as DATEL's popular AC Line Voltage Monitors (models DMS-20PC-X-LM).
