DMR20-1-FM AC Line Frequency Monitor

The DRM20-1-FM is the worlds smallest, self-powered AC line frequency monitor. The meter is fully operational when connected to an 85-264 V ac power supply and requires no additional components to support. It can measure distorted 120 Vrms power sources with triangle and square waveforms and quasi sine wave outputs of DC to AC power inverters.

The frequency monitor is housed in a rugged, round polycarbonate case that provides excellent protection against moisture, dust, shock and vibration. It has a built-in resettable fuse and out-of-range indication that assures long time reliability.

• 4-digit, 7.6 mm, LED display with out-of-range indication
• Self-powered from 85-264 V ac/45-65 Hz
• Multiple coloured LED displays available, depending on model
• 0.01 Hz resolution & quartz crystal accuracy and stability
• Digital replacement for analogue panel meters
• Self-resetting internal fuse for long-term reliability
• Supplied with EPDM rubber gasket and plastic hex nut
• Screw-style input terminal simplifies installation
• IP67/NEMA 6 protection
• Knockout punches and tooling available
