50kv 50kw Precision High Voltage DC Power Supply
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
Could accept long-term discharge sparking and short-circuiting for special-purpose environments also can be made to be 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 circuit
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 second-level protection: when the output current threshold protection control circuit detects that the output current exceeds the set threshold value, power supply immediately stops the current energy output cycle, and re-enters the next energy output cycle when the circuit resets, and the control circuit has soft-start process on new energy cycle after each reset, that is, the energy output has a rising process from zero to maximum. This control mode ensures a smooth process for each energy output.
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
HPS high-power power system has redundancy configuration inside, this design can cut off any one or a group of single-unit at any time without interrupting the operation of the entire power supply system.
The application of this technology improves the stability of some systems that cannot be powered down.

Module design
The power system adopts modular design, the front-end inverter and the rear-stage rectification are independent of each other, which makes installation and maintenance easy.

Overvoltage protection
When the output voltage exceeds the upper limit voltage set by the customer, the power supply will automatically cut off the output and alarms.

Overcurrent protection
Over current protection value 0 ~ 100% rated value continuously adjustable, power supply activates protection when current exceeds protection value.

Overload protection
Power supply has built-in overload protection circuit to prevent the power supply from being damaged due to overload.

Overheat protection
Power supply has built-in over-heat protection circuit, power supply activates protection when the temperature of the power supply radiator exceeds 75 degrees and the automatically resumes below 75 degrees.

Grid input protection
Power supply shutdown when the input voltage exceeds the range of 342V ~ 420V.

Constant voltage (CV) & Constant current (CC)
Output voltage & current continuously adjustable from 0 to rated value, CV & CC automatically switchable.

Linkage adjustment
The latest linkage adjustment technology, using a network cable to connect each module via synchronous adjustment of each module to achieve the average output of each module.

Surge limit
AC input uses active inrush current limit to reduce the impact on the grid when the input is powered on.
