Stable change machine technical parameters

Basic parameters

Protective function

Input voltage

380V±15℅(three phase) 220V±15℅(single phase) or special customization

Short circuit

Cut off the output power when the load device is shorted

Output voltage

Rated output voltage within ±5℅

Overload

When the load exceeds the rated output capacity, the output power is cut off according to the inverse time curve delay.

Frequency

50Hz/60Hz

Reverse phase

When the phase sequence of the three-phase input is wrong, the alarm will automatically cut off the output power (optional function)

Strain time

≤0.05S

Overpressure

The output exceeds the rated +10℅ (adjustable), the alarm is delayed and the output is cut off for about 5 seconds (optional alarm only does not cut off the output)

Stable schedule

The input voltage has a step change of 10℅ with respect to the rated value, and its stabilization time is ≤1S.

Undervoltage

The output exceeds the rated -15℅ (adjustable), and the alarm is turned off for about 5 seconds to cut off the output (optional alarm only does not cut off the output)

Bypass

With bypass voltage to provide power to the user equipment when the input voltage is stable or the regulator is faulty.

　

　

Other parameters

Insulation resistance

Machine-to-ground ≥2 megohms

Way of working

Long-term continuous unattended work

Withstand voltage

The whole machine is 2000VAC 1 point without breakdown, no arcing phenomenon

EMI filter device

Can effectively filter harmonic interference of the power grid (optional configuration)

Waveform distortion

No additional waveform distortion

Lightning protection device

Good surge current protection when the grid changes instantaneously and inductively strikes lightning (optional configuration)

Noise

≤55db

Monitoring interface

RS232, RS485 interface for remote control, remote signaling, telemetry (optional configuration)

Efficiency

Below 50KVA is greater than 94%, and above 100KVA is greater than 96%

1. PLG series three (single) phase stability integrated machine is a new generation of constant pressure transformer equipment developed by EECTECH with the introduction of advanced technology from Western Europe.

2. PLG series three (single) phase stability integrated machine has the functions of voltage regulation, voltage transformation and bypass; it can meet various voltage level equipments and has voltage regulation function; it is especially suitable for UPS dedicated voltage regulation bypass for large industrial enterprises. powered by.

3. This series of products has many advantages such as large capacity, high efficiency, wide voltage regulation range, stable voltage regulation and high voltage regulation accuracy. It is suitable for a wide range of loads, can withstand transient overload, and can work continuously for a long time.

4. When the voltage level of the external power supply network is inconsistent with the load voltage level and the voltage fluctuation or load changes cause voltage fluctuations, the all-in-one machine can automatically keep the output voltage stable and meet the requirements of the load rated voltage.

5. PLG series three (single) phase stability integrated machine is widely used in industrial, agricultural, transportation, post and telecommunications, oil fields, railways, construction sites, schools, hospitals, hotels, national defense, scientific research, etc. All voltage levels need to be changed (or need Isolation) and where the voltage is stable.

6. PLG series three (single) phase stability integrated machine is mainly used indoors. The normal conditions of use are:
1). Ambient temperature: -15 ° C - +45 ° C;
2). Altitude: ≤ 2000 meters;
3) Relative humidity: ≤ 90%;
4). There are no gas, steam, chemical deposits, dust, dirt and other explosive and aggressive media that seriously affect the insulation of the regulator;
5). The installation site should be free from severe vibration or bumps;
6). If you do not meet the above special conditions, please consult with EECTECH directly.
