VEME42H-D-1 Bender

Description

Product name：VEME42H-D-1 Bender output module

Product details:

The Bender LINETRAXX® VME421H-D-1 is a sophisticated voltage and frequency monitoring relay designed to continuously monitor AC/DC systems. It is part of the VME421H series, which is specifically engineered to ensure the reliable operation of electrical installations by detecting deviations in voltage (undervoltage, overvoltage) and frequency. This device measures true RMS values, making it highly accurate even with distorted waveforms.

Product Parameters (VME421H-D-1)

• Nominal System Voltage (Un): DC 9.6…150 V / AC 9.6…150 V, 15…460 Hz
• Response Value: AC/DC 9.6…150 V
• Measurement Type: True RMS value measurement (AC + DC)
• Monitoring Functions:
  • Undervoltage (< U)
  • Overvoltage (> U)
  • Frequency (< f, > f)
  • Voltage between two threshold values (window discriminator function)
• Display: Digital measured value display via multi-functional LC display.
• Relay Outputs: Two separate alarm relays (one changeover contact each), with selectable N/C or N/O operation and fault memory behavior.
• Supply Voltage: Without external supply voltage; integrated energy storage, supplied by the system being monitored.
• Adjustable Settings: Start-up delay, response delay, delay on release, adjustable switching hysteresis.
• Features: Password protection for device settings, preset function (automatic setting of basic parameters), continuous self-monitoring, internal test/reset button.
• Indicators: LEDs for Power On, Alarm 1, Alarm 2.
• Housing: Two-module enclosure (36 mm) with a sealable transparent cover.
• Terminals: Push-wire terminals (two terminals per connection).
• Compliance: RoHS-compliant.

Product Advantages

• Reliable System Monitoring: Provides comprehensive monitoring of voltage and frequency, ensuring the stability and safety of electrical systems.
• Self-Powered Operation: The integrated energy storage eliminates the need for an external power supply, simplifying installation and reducing wiring.
• High Accuracy: True RMS measurement allows for accurate readings even with non-sinusoidal waveforms, which are common in modern electrical systems.
• Versatile Monitoring Functions: Offers multiple monitoring modes (under/over voltage, under/over frequency, window monitoring) to suit various application requirements.
• User-Friendly Interface: The digital LC display provides clear measured values, and the preset function simplifies initial setup.
• Configurable Relays: Two independent alarm relays with selectable behavior (N/C or N/O, fault memory) offer flexibility for alarm signaling and control.
• Robust Design: Features like password protection and a sealable cover enhance security and protect settings from unauthorized changes.
• Compact Size: Its two-module design saves space in control cabinets.

Precautions

• Proper Installation: Ensure the device is installed by qualified personnel in accordance with all local and national electrical codes and regulations.
• Voltage Range: Verify that the system voltage to be monitored falls within the specified nominal voltage range of the VME421H-D-1 (9.6-150V AC/DC).
• Wiring: Adhere to the wiring diagrams provided in the product manual. Incorrect wiring can lead to device malfunction or damage.
• Environmental Conditions: Operate the device within its specified environmental conditions (temperature, humidity) to ensure optimal performance and longevity.
• Parameter Settings: Carefully configure the monitoring parameters (thresholds, delays) to match the specific requirements of your application. Incorrect settings could lead to nuisance tripping or failure to detect critical conditions.
• Regular Checks: While the device has continuous self-monitoring, periodic functional checks are recommended to ensure its ongoing reliability.
• Security: Utilize the password protection feature to prevent unauthorized access to device settings.

Product Applications

The Bender LINETRAXX® VME421H-D-1 is widely used in various applications requiring precise voltage and frequency monitoring:

• Single-Phase Machines: Monitoring the voltage and frequency supply to single-phase motors, pumps, and other machinery to prevent damage from power fluctuations.
• Electrical Installations: Safeguarding various electrical installations, including control panels, distribution boards, and power supply units.
• UPS Systems: Monitoring the output of Uninterruptible Power Supply (UPS) systems to ensure stable power delivery.
• Generator Sets: Overseeing the voltage and frequency output of generators to maintain power quality.
• Renewable Energy Systems: Protecting components in solar or wind power systems from grid instability.
• Building Automation: Integrating into building management systems to monitor power quality for sensitive equipment.
• Industrial Automation: Ensuring reliable power conditions for critical industrial processes and machinery.
