Performance Analysis

The Milbank MGVATS6001240 delivers reliable performance backed by its thoughtful engineering. Its core function of seamless power transfer is optimized by sophisticated sensing capabilities.

• Voltage and Frequency Monitoring: The integrated sensors constantly monitor the utility and generator power. This ensures that the transfer only occurs when utility power is lost or falls outside acceptable voltage or frequency parameters, and that the generator is providing stable power before the load is switched.
• Adjustable Transfer Delays: The potentiometers for transfer delay adjustment are a significant advantage. They allow for a delay period before the switch transfers to the generator. This can be useful to ensure the generator has reached stable operating speed and voltage, preventing abrupt power changes to sensitive equipment.
• Generator Isolation: Powering the control system directly from the genset battery and isolating it from line transients is a critical design choice. This protects the sensitive electronics from surges and interference that can originate from the utility grid or even the generator itself, contributing to long-term reliability and reducing the risk of control system failure.
• Remote Start Integration: The fused remote start contact relays provide a clean and secure way to signal the generator to start. This connection is essential for the automatic operation of the transfer switch, ensuring the generator is engaged promptly upon detecting a power outage.

Best For
