BENDER VEN420-D-1

BENDER VME420-D-1 Product Description

The BENDER VME420-D-1 (likely part of the LINETRAXX® series) is a multi-functional voltage monitoring relay. These devices are designed for continuous monitoring of electrical systems to detect deviations in voltage, frequency, and phase conditions. They are crucial for ensuring the reliability and safety of industrial power supplies, machinery, and critical infrastructure. The "-D-1" likely refers to specific configuration or measurement range.

Product Parameters (Specifications)

Based on the LINETRAXX® VME420 series, the typical parameters would include:

• Type: Voltage Monitoring Relay (Multi-functional)

• Monitored System Type:

• 3(N)AC systems (three-phase systems with or without neutral)

• DC systems (direct current systems)

• Voltage Measurement Range:

• DC Voltage: 9.6 V to 94 V (for the VME420-D-1 variant specifically mentioned)

• AC Voltage: 16 V to 72 V (for the VME420-D-1 variant specifically mentioned)

• Other models in the VMD/VME420 series can monitor up to 0...500 V AC systems.

• Monitored Parameters:

• Undervoltage: Detection of voltage dropping below a set threshold.

• Overvoltage: Detection of voltage exceeding a set threshold.

• Underfrequency: Detection of frequency dropping below a set threshold (for AC systems).

• Overfrequency: Detection of frequency exceeding a set threshold (for AC systems).

• Phase Sequence: Monitoring the correct order of phases in 3-phase systems.

• Phase Failure: Detection of a complete loss of one or more phases.

• Asymmetry: Detection of imbalances in voltage or current between phases.

• Auxiliary Supply Voltage: Often flexible, accepting both AC and DC voltages.

• Output Relays: Typically equipped with multiple alarm relays (e.g., 2 changeover contacts) to signal faults.

• Adjustable Response Values: Thresholds for voltage, frequency, and other parameters are usually adjustable.

• Adjustable Response Delays: Time delays can be configured to prevent nuisance tripping from transient events.

• Display: Often includes an LCD or LED indicators for status and measured values.

• Mounting: Designed for DIN rail mounting.
