PBDS series Bidirectional DC Power Supply
PBDS Series High Precision Bidirectional DC Power Supply adopts buck-boost conversion architecture, featuring quick dynamic response, wide output voltage range and bidirectional energy flow. Ideal match for EV/HEV MCU and motor test system, power transmission & powertrain test system, power storage and energy recycle system.
Thanks to sophisticated engineers, scientific producing workmanship, rigorous quality control systems and management team, GTAKE PBDS bidirectional DC source are equipped with advanced features, some of which are listed as below:
01 Common DC bus structure. Energy recycles in the system, while the mains supply only needs to replenish the energy loss of the system.
02 The battery simulator and drive system can share one AFE unit, saving the system hardware configuration and reducing the installation space of the test rig.
03 No matter the performance test during product development or quality control in the phase of mass production, GTAKE battery simulator and four-quadrant drive system are able to ensure the safety, precision, and best reliability according to testing requirements.
04 Switching time from -90% ~ +90% of the rated load ≤ 10ms.
05 High power factor at the grid side, ≥0.99 (when running at unit power factor) .
06 Low current THD at the grid side, <2.5% at rated power.
07 Strong overload capacity, 150% @ 1min.
08 Output voltage response time at sudden loading ≤ 5ms.
09 High-precision voltage / current regulation ≤ 0.1%FS.
10 Thorough system protection.
11 Applicable to different mains voltage in different countries..
