Product Description P/N: EHS45-600-10
Description
The Neptronic EHS45-600-10 is a microprocessor-based silicon-controlled rectifier power controller designed to regulate single-phase electric heating loads in heating, ventilation, and air conditioning systems. Rated for up to 45 amperes and 600 volts alternating current, it accepts multiple analog, pulse, and staged control signals for proportional or staged heater operation. Zero-voltage-cross switching and an integrated heat sink support stable control of electric duct heaters, baseboards, rooftop heaters, and similar resistive heating equipment.

Information About EHS45-600-10
The EHS45-600-10 is a Neptronic EHS series electronic heater controller built around a microprocessor-controlled solid-state switching architecture for single-phase resistive heating applications. The assembly incorporates one solid-state relay, a factory-installed heat sink, over-temperature protection, and a pulse status light-emitting diode for operating indication and troubleshooting. It accepts 0–10 volts direct current, 2–10 volts direct current, 0–20 milliamperes, 4–20 milliamperes, alternating or direct current pulse signals, and one-to-four-stage digital control, allowing compatibility with different heating, ventilation, and air conditioning controllers. The unit uses zero-voltage-cross firing to switch the connected heating load and is intended for applications such as variable air volume duct heaters, electric baseboards, rooftop heaters, and electric floor heating systems.
Key Features:
- 45-Ampere Load Capacity: Controls single-phase electric heating loads with a maximum current rating of 45 amperes.
- 600-Volt Maximum Power: Supports heating circuits operating at power voltages up to 600 volts alternating current.
- Multiple Control Signals: Accepts analog voltage, analog current, pulse, and staged digital control inputs for flexible system integration.
- Four-Stage Digital Operation: Supports up to four stages when configured for digital control.
- Zero-Voltage-Cross Switching: Switches the heating load near the alternating current zero crossing to reduce electrical switching disturbances.
- Integrated Thermal Protection: Includes over-temperature protection at approximately 85°C with automatic reset for controller protection.
- Factory-Installed Heat Sink: Incorporates a heat sink designed to manage thermal load during continuous power regulation.
- Pulse Status Indicator: Provides a light-emitting diode pulse indicator for operating status, servicing, and troubleshooting.
The EHS45-600-10 delivers the reliability and precision required for single-phase electric heater modulation, heating load control, and heating, ventilation, and air conditioning applications.
