SAK-24 Low Voltage Wireless Generator Load Drop

SAK-24 Wireless Load Management Introduction and Programming


Low Voltage Wireless Generator Load Drop

The SAK-24 provides a wireless solution to control loads of both normally open and normally closed devices with a dual form “C” dry contact. The contacts are rated for up to 5A and 250 VAC to control a broad range of applications. The SAK-24 is powered by 24 VAC that can be derived from anywhere within the electrical system. A connection or control wire back to the generator or transfer switch is not required.

When a power outage occurs, and power is restored, the SAK-24 will energize the relays and begin to analyze the AC power from the input. When utility power is detected the SAK-24 will de-energize the relay after 2–5 minutes and enter into a sleep mode until the next outage occurs. When generator voltage is detected the relay will remain energized and the SAK-24 will continue to monitor the AC line waveform. When utility power returns, the load will be restored after 2–5 minutes and the SAK-24 will enter sleep mode until a power outage occurs.
