Products Description
Product overview
The ZPHC3 series multifunctional bidirectional DC power supply employs a three-phase PFC feed-back design and pure digital PWM rectification technology. Its AC-DC bidirectional conversion utilizes four-quadrant SVPWM technology, enabling bidirectional energy flow with a power factor exceeding 0.99. Featuring 100% energy feedback and minimal grid current pollution, it delivers an input power factor>0.99 while maintaining rated operational harmonics <3%. Meeting China's GB/T14549-93 standard requirements for power quality harmonics in public grids, this high-performance device ensures precise output accuracy, rapid dynamic response, and complete grid energy feedback. Widely applicable to R&D, type testing, reliability evaluation, and production line testing for new energy vehicle motors, electronic control systems, battery pack charge/discharge testing, and other power electronics applications. It fulfills GB/T18488.1-2015,
GB/T18488.2-2015, GB/T29307-2012 test requirements for the use of power supply.
· Battery simulation function can simulate the characteristics of charging and discharging of various batteries. Users can choose to simulate different battery types, series number of batteries, parallel number of batteries and SOC indicators, so as to comprehensively simulate the output characteristics of batteries, including the process of internal resistance characteristic change during battery discharge;
· Programmable DC power function has constant voltage, constant current and constant power mode output, can be automatically cross-transformed, maintain the characteristics of control and protection, ensure high precision, low ripple, fast dynamic response speed of voltage and current of DC power output;
· DC load function has constant resistance, constant voltage, constant current, constant power and other functions; Note: multiple output channels can be customized, and the channels can be used in parallel.
Product features
· Three-phase P.F.C feedback design. The system adopts two-level AC-DC and DC-DC bidirectional transformation architecture, which can effectively stabilize the fluctuation of bus voltage during sudden addition, thus improving the dynamic response time of the whole machine output and complete electrical isolation;
· The AC-DC bidirectional conversion adopts four-quadrant SVPWM technology, with bidirectional energy flow and power factor up to 0.99 or more. The network harmonic pollution is small, the feed grid current pollution is small, the input power factor is high:>0.99, and the rated working harmonic is less than 3%;
· Intelligent monitoring function, friendly man-machine interface, can be controlled remotely through CAN bus or PC;
• Features constant voltage, constant current, and constant power functions with adjustable voltage/current ranges from 0-100%, supporting dual-mode operation for both power supply and load. Unlike traditional power supplies that match their rated output voltage, our system delivers significantly higher maximum output voltages. The power supply maintains constant power output even when exceeding rated voltage levels, thereby maximizing its operational capacity.
