The FreqMon2005 is an AC frequency Monitor. It uses a microprocessor based integrated circuit design to acquire a highly accurate frequency reading. The wide input voltage range, 100VAC – 300VAC, allows for easy direct replacement of 120, 240 & 277VAC 3” meters. The easy to read LED design makes it ideal for use on PTO generators to quickly determine the frequency while adjusting the tractor throttle. It’s a helpful accessory in a Motor Home to clearly indicate that the generator is producing voltage at the correct frequency. The wide voltage range makes it ideal for all standard voltage configurations up to 480V (line to neutral).
