VWKP240A中文资料Voltage Monitor Relays数据手册Macromatic规格书

描述 Description

The relay energizes (and the LED is Red) when the monitored voltage is between the over and under voltage settings.The relay de-energizes (and the LED is Green) when the monitored voltage falls outside the over or under voltage settings for a period longer than the drop-out time delay (t), which is adjustable between 0.1-10 seconds.The relay re-energizes when the monitored voltage returns to a value between the over and under voltage settings for a period longer than the fixed pick-up time delay of 0.5 seconds.

应用 Application

• Voltage Tolerance: +50%/-50% of nominal AC voltage (50-60Hz, +5%) or DC voltage; No separate input voltage is required since unit is powered by monitored voltage.
• Load (Burden): Less than 2 VA (12-120V); 30VA (240V & 480V)
• Voltage Settings: Over Voltage (Umax): Adjustable across full range as shown on the product nameplateUnder Voltage (Umin): Adjustable from 75-95% of the Over Voltage setting
• Response Times: Pick-up: 500 ms;Drop-out (t): Adjustable 0.1-10 Seconds
• Indicator LED: Red when Relay is energized; Green when Relay is Off
• Output Contacts: 10A @ 240V AC, 7A @ 30V DC, 1/4HP @ 120/240V AC, C300
• Life: Mechanical:10,000,000 operations; Full Load:100,000 operations
• Temperature: -28o to 65o C (-18o to 149o F)
• Approvals:
