Technical Specifications and Physical Characteristics

Understanding the exact specifications of the GE HEC-GV3-DNG ensures proper integration into your existing control cabinet. This power supply features robust construction with multiple protection circuits for industrial environments.

Input and Output Power Specifications

The GE HEC-GV3-DNG accepts a wide range of input voltages for global application flexibility. Its regulated output ensures sensitive electronics receive clean, stable power.

• Input Voltage Range: The module accepts 85 to 264 V AC at 47 to 63 Hz. Additionally, it supports 120 to 370 V DC input for versatile installation options.

• Output Voltage: It provides a regulated +24 V DC output with ±1% tolerance. This stable voltage suits most GE control modules and field devices.

• Output Current: The supply delivers up to 10 Amps of continuous current. Consequently, it can power multiple modules from a single unit.

• Output Power: Maximum continuous output power reaches 240 Watts. This capacity supports medium-sized control system configurations.

• Efficiency Rating: The GE HEC-GV3-DNG achieves 88% typical efficiency at full load. This reduces heat generation and energy costs over time.

Energy Storage and Protection Features

Reliable operation of the GE HEC-GV3-DNG depends on its internal energy storage and protection circuits. These features safeguard both the supply and connected equipment.

• Hold-up Time: Internal capacitors provide 20 ms hold-up time at full load. Therefore, the output remains stable during brief AC power interruptions.

• Inrush Current Limiting: Built-in circuits limit startup inrush current to 30 Amps maximum. This prevents nuisance tripping of upstream circuit breakers.

• Overload Protection: The supply automatically enters constant current mode during overloads. It recovers normally once the fault condition clears.

• Overvoltage Protection: Internal clamping circuits limit output voltage to 30 V DC maximum. This protects connected modules from damaging voltage spikes.

• Short Circuit Protection: Electronic shutdown occurs during output short circuits. The module attempts automatic recovery every 5 seconds.

Environmental Specifications and Operational Reliability

The GE HEC-GV3-DNG operates reliably across a wide range of environmental conditions. Its robust design suits demanding industrial automation applications.

• Operating Temperature: The module functions from -25 to 70 degrees Celsius. Derating applies above 60 degrees for continuous operation.

• Storage Temperature: It withstands storage from -40 to 85 degrees Celsius. This tolerance accommodates shipping and warehouse conditions.

• Humidity Rating: The supply operates at 5% to 95% relative humidity without condensation. This protects internal components from moisture damage.

• Vibration Resistance: It withstands 2G vibration from 10 to 500 Hz. This ensures reliable operation in high-vibration environments.

• MTBF Rating: Mean time between failures exceeds 500,000 hours at 25 degrees Celsius. This demonstrates exceptional long-term reliability.

System Integration and Applications

Integrating the GE HEC-GV3-DNG into your control system requires straightforward wiring and configuration. It works alongside modules like the IS200AEBMG1AFB in broader GE automation architectures.

• Input Connections: The terminal block accepts solid or stranded wire up to 12 AWG. Clearly marked terminals simplify installation and reduce wiring errors.

• Output Connections: Separate terminals provide +24 V DC and common connections. Remote sense terminals compensate for voltage drop in long cable runs.

• Status Indication: A green LED indicates proper output voltage presence. Red LED illuminates during fault conditions for quick troubleshooting.

• Parallel Operation: You can connect multiple GE HEC-GV3-DNG units in parallel for redundancy. This configuration supports critical applications requiring continuous uptime.
