100 Amp Cronos Controller Unit (GPS)

•  Rugged M. C. Miller Co. design, highly reliable, easy to operate and very competitively-priced.
•  Precision clock-timing even with an intermittent view of the GPS satellites.
•  Two years of continuous (current interruption) operation on a single set of replaceable "D" cell batteries - no need to recharge the unit every few days
•  Easy to program via a PC or can "quick select" via the keypad
•  Integrates with 100A relay (external relay) rated at 120V AC/DC
•  Solid-state (non-polarity dependent) relay - no unit orientation or polarity concerns
•  Only 1mV dropped across the relay per Amp - both small and large currents can be interrupted
•  Fully-automated current-interruption programs can be started in the field with the push of a single button.

100A Cronos units ship with the following items:

•  Cronos-to-PC cable (RS232 cable with USB adapter)
•  Cronos-to-Cronos communication cable



Maximum Current:

100 Amps at 120V (12,000 watts) external relay

Maximum Working Voltage:

170V DC (either polarity), 120Vrms (50/60Hz)

Voltage Drop:

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.
