BENDER繼電器VME421H系列介紹
VME421H系列電壓繼電器設(shè)計(jì)用于監(jiān)控交流和直流系統(tǒng)中的頻率、欠壓、過壓以及兩個(gè)閾值之間的電壓（窗口鑒別器功能）。電壓以有效值測量。當(dāng)前測量值連續(xù)顯示在液晶顯示屏上。將存儲(chǔ)導(dǎo)致報(bào)警繼電器激活的測量值。由于響應(yīng)時(shí)間可調(diào)，可以考慮特定于安裝的特性，例如特定于設(shè)備的啟動(dòng)程序、短時(shí)電壓波動(dòng)等。設(shè)備版本 VME421H 從受監(jiān)控的系統(tǒng)獲取電源電壓并利用內(nèi)部備用能源。

The voltage relays of the VME421H series are designed to monitor the frequency, undervoltage, overvoltage and the voltage between two threshold values (window discriminator function) in AC and DC systems. The voltages are measured as r.m.s. values. The currently measured value is continuously shown on the LC display. The measured value leading to the activation of the alarm relays will be stored. Due to adjustable response times, installation-specific characteristics, such as device-specific start-up procedures, short-time voltage fluctuations, etc. can be considered. Device version VME421H takes the supply voltage from the system being monitored and utilizes an internal energy backup.

? Integrated energy backup
? Different monitoring functions selectable < U, > U, < f, > f
? Start-up delay, response delay, delay on release
? Adjustable switching hysteresis
? r.m.s. value measurement (AC + DC)
? Digital measured value display via multi-functional LC display
? Preset function (automatic assignment of basic parameters)
? LEDs: Power On, Alarm 1, Alarm 2
? Measured value memory for operating value
? Continuous self monitoring
? Internal test/rest button
? Two separate alarm relays (one changeover contact each)
? N/C or N/O operation and fault memory behaviour selectable
? Password protection for device setting
? Sealable transparent cover
? Two-module enclosure (36 mm)
? Push-wire terminal (two terminals per connection)
? RoHS-compliant
