LOVATO|DMK70R1 Voltage Monitor 3 Phase

Digital meters(measuring and monitoring instruments)

DMK modular digital monitoring devices

• Auxiliary supply: 220 – 240 VAC
• 1 changeover relay output (8A 250 VAC)
• Instantaneous or preset trip delays (0 – 900sec)
• Modular DIN rail mounting (3 modules €’ 54 mm wide)
• Memorises minimum and maximum measured values (since last reset)

Voltage monitors (measures and displays single and three phase voltages)

• Overvoltage range: Off / 102 – 120% (delay 0 – 900sec)
• Undervoltage range: Off / 70 – 98% (delay 0 – 900sec)
• Voltage/phase loss or failure: Off / 5 – 85% (delay 0 – 900sec)
• Programmable PT ratio : 1.00 – 500.00 (accuracy: ±0.25% f.s. ±1digit)
