Frequency Monitor
The Model 29 Frequency Monitor provides essential oversight for industrial electrical systems. It precisely monitors frequencies within a 40Hz to 70Hz range, with an extended 320Hz to 560Hz option via jumper. Operating across an 80-550 VAC input, this unit ensures consistent performance. Dual SPDT output contacts, rated at 10 Amps for 240VAC, offer robust control capabilities. Configurable high and low frequency set points, along with adjustable trip delays and hysteresis, allow for tailored system protection. Its Lexan Polycarbonate enclosure and -20°F to +130°F operating temperature range ensure durability in demanding environments. Repeat accuracy is maintained at ± 0.5%. Automatic or manual restart options further enhance operational continuity, minimizing downtime. This monitor is a reliable component for maintaining system stability.
