Product Information
ATOM is an ultra-compact, low cost, microprocessor-based power controller to assist with control of AC or DC loads.
ATOM is available in three models varying in connectivity:
- Analog
- Digital (Ethernet/IP, ModbusTCP, or PROFINET)
- EtherCAT
For ATOM Three Phase controllers, resistive or transformer-connected loads can be controlled in multiple ways, including SSR On/Off Relay, Zero Cross, or Fast Zero Cross. Output is controlled linearly and can be set to the average or RMS value of the voltage or current.
ATOM Three Phase controllers offer the following features:
- 2 SCR (3-phase 2-leg configuration)
- Auto-ranging voltage circuitry to enable main supply voltage (45-65 Hz)
- 24-600 VAC for UL/cUL
- 24-600 VAC for CE
- Robust design for continuous full-frame current operation without derating, up to 122°F [50°C], 6000 ft [1829 m] altitude
- 24 Vdc power source to supply control electronics and maintain critical communications
- Control setpoints through standard analog or optional digital fieldbus interfaces
- Analog control
- Standard: 0-5 VDC, 4-20 mA setpoints
- Field Scalable: 0-10 VDC, 0-20 mA.
- On/Off Relay Mode: 0, 4-32 Vdc
- Status LEDs and an LED bar graph to quickly monitor operating status
- Plug-n-play USB-C interface and free Control Panel software
- Ability to easily duplicate controller settings for multiple controllers
OEM options may be available upon factory consultation.
