Product Introduction
ETCR5600 Phase-Changing Low Voltage Correction Device is a real-time and intelligent automatic load control device developed by our company, which is used for on-load phase-changing of single-phase loads, effectively solving the low voltage problem caused by the three-phase imbalance of the low-voltage distribution network. In the low-voltage distribution network, the voltage of a certain phase is too low due to the three-phase imbalance, causing the single-phase load in that phase to fail to work properly. The phase-changing low voltage correction device monitors the incoming three-phase voltage in real time and automatically switches the load from the low-voltage phase to the high-voltage phase. During the switching process, the power supply is not interrupted, and the operation of the equipment will not be affected to ensure the normal operation of the load. The device has two phase-changing modes, manual phase-changing and automatic phase-changing.Manual phase-changing mode: The user can manually switch the load to any phase of A, B, and C for power supply to meet the needs of the user's special circumstances.Automatic phase-changing mode: The device automatically switches the load from the low-voltage phase to the high-voltage phase to ensure the normal operation of the load.
ETCR5600 Phase-Changing Low Voltage Correction Device adopts a modular design, compact structure, simple installation and easy operation. The device has a Bluetooth communication function, which can perform operations such as command threshold setting and observe the operation of the commutator switch in the mobile terminal.
1. Using a unique seamless phase-changing technology, the on-load phase-changing does not interrupt the power supply, no voltage drop, no surge current, and has no effect on the sensitive load.
2. Adopt interphase interlocking technology between hardware and software, and there is no risk of interphase short circuit.
3. There is no surge current in the phase-changing process, and the phase-changing is stable and reliable.Since the phase-changing time is zero milliseconds, the phase transition of the phase-changing process is only 120° at the time when the two-phase voltages are equal, which is a natural phase-changing, so there is no voltage mutation and no surge current.
4. It has no adverse effects on all kinds of electrical equipment.The seamless phase-changing technology of equal voltage of 0 milliseconds will not cause power supply interruption and voltage drop, and will not affect the user's electricity consumption at all; it can be stably and reliably phase-changing for inductive, capacitive, and resistive loads.
5. It has an automatic bypass function. When the fuse of the input phase is blown, the commutator will stop phase-changing and automatically switch the load to the current phase to maintain the user's power supply. After the fuse is replaced, the commutator can resume normal operation.
6. With Bluetooth communication function, you can operate the phase-changing device through your mobile phone to check the load and the working condition of the commutator.
7. It is equipped with an outdoor box, which can be installed and used outdoors.Long phase-changing life: The number of phase-changing of the commutation device is greater than 200,000 times, and it can be used for 8 to 10 years.
