  • Service
  • Before the order is made, we can provide customers with accurate and detailed technical data, while samples are also available though customers need to pay for the samples and corresponding freight. Meanwhile, customers are allowed to come to our factory for an on-site inspection about the production flow, quality control and product test. For those clients that have built up a long-term cooperative relationship with us, they can try our new products free of charge except the freight.

    1. Low Frequency Power Inverter with Charger
    2. Low Frequency Power Inverter with ChargerIt is a universal product that is suitable for various kinds of inductive, capacitive and resistive loads, making it applicable for televisions, refrigerators, computers, electric fans, air conditioners, cash registers, washing machines, electric tools, water pumps, microwave ovens, incandescent lamps, energy saving lamps, etc. Meanwhile, it also shows good stability, pure sine wave output and excellent overload capability.
    1. Industrial Pure Sine Wave Power Inverter with Charger
    2. Industrial Pure Sine Wave Power Inverter with ChargerThe three-step charging technology divides charge profile in three phases which are bulk charge, absorption charge and float charge, thereby enhancing battery performance to a large extent. Two working modes which are battery mode and mains supply mode, could be switched automatically.
    1. High Frequency Online UPS
    2. High Frequency Online UPSThe online double conversion method is able to support the protected equipment with continuous green power supply, and this method refers to accepting AC input, rectifying to DC for passing through the rechargeable battery, then inverting back to AC output. Thus, the key electrical appliances will not be affected by power failure, instable voltage, frequency variation, harmonic distortion and other anomalies.
    1. Relay Control Digital Single Phase Voltage Stabilizer
    2. Relay Control Digital Single Phase Voltage StabilizerThis device contains different models, and all of them are provided with complete protections including overvoltage protection, under voltage protection, delay output protection, temperature protection and fault protection. These functions make our product work in a more reliable way. In addition, the overvoltage, under voltage and delay time protections could be adjusted by user.
    1. Three Phase Full-Automatic Compensated Voltage Stabilizer
    2. Three Phase Full-Automatic Compensated Voltage Stabilizer In contrast to other types, this device possesses higher efficiency, larger capacity, no waveform distortion, balanced voltage regulation and other advantages. It is also characterized by small size, light weight, reliable running, convenient installation, free switch between manual mode and automatic mode, etc.
    1. 7-Stage High Frequency Intelligent Battery Charger
    2. 7-Stage High Frequency Intelligent Battery ChargerThe 7-stage charging is a very comprehensive and accurate charging technique that gives the battery longer life and better performance when compared to using traditional chargers. This product is applicable for most types of battery including GEL, Calcium and Lead-Acid, and it can also help restore drained and sulphated batteries.
    1. Deep Cycle Maintenance Free GEL Battery
    2. Deep Cycle Maintenance Free GEL BatteryThe specially designed plate shows ultra high porosity, and the radial shaped plate grid adopts tight assembling technique, guaranteeing excellent high rate discharge performance. Due to the ultra thin glass fiber technology, the gas recombination rate is over 99%, and the internal resistance is very low.
    1. General Variable Frequency Drive
    2. General Variable Frequency DriveThe product adopts the SVC current vector control mode, and is optional with V/F control mode. It is configured flexibly with multi-node setting for V/F curve. The equipment is also avilable with motor parameters static self-turning function. It is outfitted with the multifunctional programmable input port, allowing for programming relay output.
