Victron Energy Victron (Ziehl) Voltage and Frequency Relay UFR1001E

The UFR1001E mains decoupling relay monitors voltage and frequency in three-phase and alternating current mains. It complies with the following conditions:

VDE-AR-N 4105:2018-11

• Central NA protection in self-generation systems for feeding into the low-voltage grid
• The program contains two corresponding parameters, as well as adapted monitoring of the coupling switch and protection of parameters
• The relay has a dual-channel and interference-proof design

VDE-AR-N 4110:2018-11

• Unit protection at the generating units and as intermediate NA protection for feeding into the medium-voltage grid
• Use as higher-level NA protection is possible if no Q-U protection is required

Properties

• Undervoltage/overvoltage monitoring 15-520V (with voltage transformers up to 1000V)
• Measurement against N and/or phase-phase
• Under/overfrequency monitoring 45-65 Hz
• Voltage quality monitoring (10-minute average) and zero voltage
• Alarm counter for 100 alarms (with trigger value, cause, and relative time stamp)
• Standby input with counter and time memory, remote shutdown possible
• Test button and simulation function with measurement of switch-off times
• Easy commissioning and programming due to preset basic programs
• Preset limit values for various applications

Scope of delivery:

1x Victron (Ziehl) UFR1001E.
