52421
SOLID STATE THERMOSTAT CONTROLLER
Space Application Series...
Mii
HYBRID MICROELECTRONICS
PRODUCTS DIVISION
Features:
Operates With RTD Temperature Sensor
Output Is Either “ON” Or “OFF”
Standard And Custom Factory Settings Of:
- Resistance Control Set Points (Temperatures),
- Hysteresis, (Minimum/Maximum) And
- Timing (On/Off Delays)
- Test (Load Power On/Off) Capability
Optional Mounting Configurations Available
Applications:
Meets The Demanding Requirements Of Space
Platform Environments, Where Precise
Temperature Control Is Required.
DESCRIPTION
Micropac’s Space level Thermostat Controller 52421 operates with external RTD (Resistance Temperature Device)
temperature sensor and provides a power switched (On / Off) output within a temperature window. The RTD sensor is
conditioned then controls a high-side MOSFET power switch for an external HEATER.
Models are available with dual channels providing either “OR” or “AND” configurations.
Wired combinations of the “OR” configuration device, along with a single channel device, provides a tri-redundancy
control system which guarantees both the power ON and power OFF states of the Heater
