Automatic reconnection adjustable voltage,current, and energy metering protector JGDL-63
JGDL-63 is an energy metering type current limiting protector, which provides multiple protection functions for overvoltage, undervoltage, overcurrent, leakage, temperature, frequency, and energy meteringThe comprehensive protector of Neng can set all protection
Automatic reset overvoltage and undervoltage protector JGGQ-63
JGGQ-63 Automatic reset overvoltage and undervoltage protector adopts the control circuit with high-speed micro-low-power processor as the core, magnetic latching relay as the main circuit, and modularized standard design, when the power supply line appears overvoltage and undervoltage, the protector can quickly and safely cut off the circuit under the continuous high-voltage impact to avoid the occurrence of accidents caused by abnormal voltage sent to the terminal electrical appliances, and when the voltage returns to normal values, the protector will automatically turn on the circuit within the specified time to ensure the normal operation of the terminal appliances in the unattended situation.
Over Voltage And Under Voltage Protector JGGQ-80
After 10 years of technical precipitation, N times of testing and technical improvement, JGGQ-80 self-resettable over-under-voltage protector is on the market, using high-speed micro-low-power processor as the core of the control circuit, magnetic latching relay as the main circuit, and modularized standard design, which has the technical advantages of low power consumption, precise control, beautiful appearance, anti-harmonic, anti-interference, and withstand voltage up to AC450V.
Three-phase four-wire self-resetting over-under-voltage protector JGGQ-80S
Three-phase four-wire self-recovery over-under-voltage protector is an upgrade from the ordinary type of product, product features: low power consumption, long life, precise control, phase loss protection, lack of zero line protection, maximum short-circuit limiting current 3000A, software control humanization, and clear indication with Led light, the product is powered on for the first time under normal conditions of the power supply closing time is 6 seconds, when the line occurs over-undervoltage, lack of phase and other faults, when the power supply turns normal, the closing time is 40 seconds, this design saves too much time to wait when the power grid is in the power failure.
