1-PHASE HIGH VOLTAGE AND 1-PHASE LOW VOLTAGE

• Network parameters monitoring
• Remote access via GSM network
• Redundant operation with battery
• Outside construction
• Max. current feed through 18A (60VAC)

In case the power goes off you can continuously monitor the parameters because there is a built-in battery.
Monitor is done by standard SNMP protocol. Neccessary MIB files are available free of charge.
Sample rate is 40ms. PSU monitor makes average values -from network parameters- and supervises the below mentioned parameters regarding the EN 50160:
1) Overvoltage: The 40ms average value is 10% higher than the nominal value. The voltage should be lower then the 110% average value to cancel overvoltage.
2) Dip: The 40ms average value is 20% lower than the nominal value. To cancel voltage should be minimum 90% of nominal value.
3) Voltage failure: Voltage falls under the 10% of nomimal value. To cancel voltage should be minimum 90% of nominal value.
4) Vibration: 5% – Instantaneous voltage chanching value (the 40ms average value minus previous value in absolute value) is bigger or equal to 5% of nominal voltage value but lower then 10% of nominal voltage. 10% – Instantaneous voltage chanching value (the 40ms average value minus previous value in absolute value) is bigger or equal to 10% of nominal value.
