Founded in 1995, China Dongda Power Industry Co., Ltd. is one of the few high power supply manufacturer and distributor in China that has patents on the generator, motor, power supply, engine, alternator, diesel and gearmotor design, supply and sale. Our custom high power supplies has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS and we have won EPA 2005 Motor Year Certification. Our 30 QC staff carefully performs inspections at every stage of production, from the time we receive raw materials to packaging. Noise, power, and stability are tested to ensure that our engines can endure 580 hours of constant use. We also can design and deliver OEM/ODM samples in one month.

The ACP-4000 is a 4U-high 14-slot rackmount industrial computer chassis designed for building mission-critical applications. The unit includes a versative 14-slot passive backplane (optional), high-efficiency 300W ATX with PFC (Power Factor Correction) power supply, dual easy maintenance cooling fans, and supports ATX M/B form factor. A fault detection and alarm notification system monitors the systems status. A wide range of standard computing peripherals can be integrated with the chassis to meet different application requirements. Wide range of input voltage, high efficiency, high power factor, high power density, high intelligence, and compact structure. PRS6300 system includes SMPS6300 rectifier module, CU6300 control module, PRS6300 rectifier rack, AC and DC distribution. Dimensions (W x D x H): 600 x 600 x 2,000mm. Weight: 545kg (includes 20 rectifier modules). Also generating less heat, and enabling cooling with a smaller, slower, quieter fan. Active PFC circuitry further reduces impact on the power infrastructure.

High effect and high precision. The linear constant voltage circuit is compose of big power transformer, audion,commutate bridge, big capacity electrolyte in order to confirm the advance indexes,good
stability and thunder- proof. Input voltage: 220V AC±10%, 50Hz (60Hz). Output voltage: 13.8V DC ±0.2V DC. Output current: rated: 25A max.: 35A. Ripple voltage: <5MV (peak to peak). Operating environment: -10oC-50oC. Dimension (L x W x H): 132 x 380 x 240mm. Weight: 13kg. 430-watt energy-efficient operation reduces power consumption by up to 20% compared with traditional power supplies. Generates less heat, enabling cooling with a smaller, slower, quieter fan. Active PFC circuitry reduces impact on the power infrastructure. One super-silent 80mm fan keeps Neo HE cool; less than 18dBA noise level. Advanced Cable Management System improves internal airflow and reduces system clutter by allowing you to use only the cables you need.
