Thermal Management Systems

Thermal Control Electronics for space applications

Thermal Control Electronic Units are multi-channel, closed-loop, analog, heater controllers. Rated for use in GEO orbit (e.g., satellite busses, launch vehicles, and payloads), the robust design and construction apply to numerous aerospace use cases. Each channel has an independent on/off heater output driver, an associated temperature sensor, and an externally configurable setpoint. This channel-specific setpoint will correspond to a temperature for which the Thermal Management Unit will ‘turn on’ its heater when its associated temperature sensor senses the setpoint temperature. The heater will turn off when the temperature sensor warms to a fixed hysteresis value above the setpoint temperature. SOE MOTS Thermal Control Electronics supports 2-wire and 4-wire RTDs for temperature sensing and pre-manufacturing customizable hysteresis.
