HPS High Power High voltage DC Power Supply Model: HPS-(N/P)150KW-100KV | ||||
|  | |||
| Overview | ||||
| The HPS series is developed based on the HP series power supply with internal modules in parallel-connection. This series of power supplies are featured for excellent electronic characteristics such as high accuracy, high precision and high stability. Its output voltage ranges from 5KV to 300KV, and its power rating has reached a wide range of 50KW ~ 1000KW. The power supply adopts hybrid cooling mode: Air-cooling for the control part, water cooling plus oil-cooling for main power components, internal module redundancy technology and perfect protection circuit to ensure the excellent reliability of the power supply under high voltage and high-power output. The power supply is mainly customized according to the applications, and the industries we have engaged includes mining gravel, super power capacitor charging, electron beam melting, and ray tube veteran etc. | ||||
| Features | ||||
Short circuit protection High-voltage power supply is equipped with a special output current short-circuit suppression circuit to prevent high-voltage power supply output discharging and sparking short circuitCould accept long-term discharge sparking and short-circuiting for special-purpose environments also can be made to be short-circuit protection. The high-voltage power supply is equipped with a special discharging protection circuit to ensure that other equipment and the power supply are not damaged. Ultra-short protection time: When the sensitive current detection circuit detects that the current exceeds the protection set value, power supply would enable the current-limit & power-limit circuit to ensure that the output current is controlled within the set value. The protection startup time is within 10 microseconds and can be achieved in 3 microseconds as requirements. Double current-protection circuit The first-level protection: The dynamic current detection control circuit stabilizes the current at the set value dynamically. The power supply voltage-drop flash detection circuit detects short-circuit and sparking condition of the load at the first time, and enables the protection circuit in time. Redundancy technology The application of this technology improves the stability of some systems that cannot be powered down.
