Operating time counters

Working hours counters type HC48 are designed to determine the operating time of equipment in order to monitor compliance with warranty periods and intervals of preventive maintenance of various electrical equipment units. The meters are connected in parallel to the control circuit of the installation, directly behind the starting device, so they only measure the net operating time of the equipment.

Specifications:

• Supply voltage AC: 24V, 110V, 230V, 400V (+/- 10%) DC: 10-48V, 110V (+/- 10%)
• AC mains frequency: 50Hz, 60Hz
• AC and DC protection class: IP40 - front panel
• Operating temperature range AC: -25C… + 80C; DC: -25C ... + 70C
• Accuracy of AC readings: 1/100 hour (36 sec.); DC: 1/10 hour (6 min.)
• AC count range: 99,999.99 hour; DC: 999,999.9 hours
• Number of AC characters: 5 integers, 2 decimal; DC: 6 integers, 1 decimal

Working hours counters type HC 36/24 are designed to indicate the operating time of various electrical equipment units, for example, electric motors, electric furnaces, central heating boilers, rectifiers, etc. The meters are connected in parallel to the control circuit of the installation, directly behind the starting device, so they only measure the net operating time of the equipment.

Specifications:

• Supply voltage AC: 24V, 110V, 230V (+/- 10%) DC: 12-36V, 110V (+/- 10%)
• AC mains frequency: 50Hz, 60Hz
• AC and DC protection class: IP40 - front panel
• Operating temperature range AC: -25C… + 60C; DC: -25C ... + 60C
• Accuracy of AC readings: 1/100 hour (36 sec.); DC: 1/10 hour (6 min.)
• AC count range: 99,999.99 hour; DC: 999,999.9 hours
