Maximum Current: 100 Amps at 120V (12,000 watts) external relay
Maximum Working Voltage: 170V DC (either polarity), 120Vrms (50/60Hz)
Voltage Drop: 11.1mV per Amp Suitable for interrupting low Voltage bonds and anodes
Overload Protection: 75kW(10/100µs); 500kW(8/20µs) 1.2kA peak @ clamp voltage. Auto thermal shutdown at 105oC.
Isolation to ground: 12,000 Volts
Power Consumption: Runs on 2 “D” Cell batteries (3.6V, 19Ah)
Battery-life depends on programmable settings – 2 years continuous operation typical on default settings.
Time Standards: UTC (default) or GPS; Synchronization @ 00.00 (default) or @ start time; Local –Offset; user defined to ensure consistency
Clock/Interruption Accuracy: 1ms max. deviation with satellites in view
0.5 ms per hour without satellites in view
Re-acquires precision time when satellites return to view
Temperature compensated range: -40oC to +85oC.
Temperature Range: Relay Operation: -40oC to +85oC
LCD Operation: -20oC to +70oC
Dimensions: Control Unit: 9in x 11in x 3in
Relay Unit: 13.5in x 7in x 4in
Weight: Control Unit: 5.6lbs
Relay Unit: 19.4lbs
Multiple Unit Programming:
Cronos PC software allows personal settings to be created and saved for future download to Cronos units, or a “master” Cronos unit can
be used to automatically program other Cronos units.
• On/Off 0.1 to 99 sec. 0.1 sec increments
• Start and stop date and time
• Begin cycle with relay open or closed
• Close relay at end of work day
• Start cycle at beginning of work day
• Switching offsets ±500ms (both On-to-Off and Off-to-On) – allows for use of other relay types.
