Preen AC & DC Power Supplies

The ADG+ series high-power DC supply offers up to 300kW per unit, low ripple, and high accuracy. It can simulate solar arrays with an I-V curve function. With output up to 2000V, 1800kW, and 2500A, it suits EV motors, DC/DC converters, ESS, and inverters.

Features:

• Wide range of output voltage up to 2000V.
• Simple master-slave operation, output power can up to 1800kW via parallel connection.
• Low ripple ≤0.05% and high accuracy ≤ 0.1%.
• Fast response ≤ 6-20 ms
• Optional I-V curve function for Solar Array Simulation (built-in EN50530 mathematical formula).
• Large 7" touch screen and rotary knob for easy operation and measurement display.
• Time setting resolution 0.01S for fast response programming testings.
• Capable of simulating all kinds of load testing conditions: step or consecutive voltage variation can be set via STEP and Gradual function.
• Remote Sensing Compensation.
• Equipped with emergency stop button, which meets the requirement for laboratory related testing field.

The AFV series programmable AC power source is ideal for home appliances, electronics, medical equipment, and lighting. It offers up to 2,000kVA with high accuracy and fast response, supporting 0-310V and 45-500Hz. Communication options include RS-485, RS-232, Ethernet, GPIB, and Analog. Features include STEP and GRADUAL programming, three-phase control, and soft start.

Features:             

• CE & RoHS certificated.
• Modularized inverter which is compact, smaller, high power density and easy to maintain.
• 7-inch touch screen which can display the phase voltage, current, frequency, active/apparent power, power factor and test information.
• Ability to simulate abnormal power status: STEP and GRADUAL modes allow users to set sequences of start/end voltage, frequency and running time with ease.
• Comprehensive protections which include output undervoltage / overvoltage, overcurrent, overload, input undervoltage / overvoltage, overheat and other more than twenty fault conditions.
• Three-phase voltage independently adjustable function: each phase voltage can be adjusted independently; therefore AFV can power more than one single-phase loads.
• Phase angle adjustment function: can adjust the phase angle between each phase (for three phase system).
