AVR & IVR Differnce
Product | A.V.R.-Automatic Voltage Regulator | I.V.R.-Induction Voltage Regulator |
Structure | With carbon brush. With 3 PCB and 3 regulator. | With Induction Voltage Regulator without brush. With stator and rotor. |
Feature | Reaction time: 0.1 seconds With H class (highest) material Three PCB control each phase Three regulator control each phase Central shaft with aluminum material good for reduce heat Interior consists of induction voltage regulator. IVR with brushless type components. None consume material need to change even long term usage. Minimum no-load loss, load loss, and no-load current. | Interior consists of induction voltage regulator. IVR with brushless type components. None consume material need to change even long term usage. Minimum no-load loss, load loss, and no-load current. |
Protection | Instant electricity shutdown delay protection Phase-shortage protection Over voltage protection Low voltage protection Overload protection Short circuit protection With Bypass switch | LED Panel & Alarm Over voltage protection Low voltage protection Loss phase protection Reversed Phase protection Over temperature protection Motor relay off protection Manual adjustment |
Specification | 1Φ0.5KVA~100KVA 3Φ5KVA~600KVA | 3Φ100KVA~5000KVA |
Cost | Over 200KVA, cost will be much higher than IVR | Below 150KVA, cost will be much higher than AVR |
Usage | Basically, one AVR for one machine | One IVR for many machine or whole factory |
