Overview

0 to 100 volt variable high voltage power supply provides 3000W/5000W output power and up to 30 amp/50 amp current capacity for industrial testing, laboratory use, and equipment verification, available with optional single-phase 110V/220V input, overvoltage and overload protection.

Feature

Constant Voltage & Current Mode: Voltage and current values are continuously adjustable from 0-100 volt and 30 amp/50 amp.
PWM Switch Control: Adopts PWM technology, offering lightweight, high efficiency, high precision and low ripple.
High Adaptability: PowerHome variable DC power supply is suitable for resistive, capacitive and inductive loads with excellent performance.

Details

Convenient Operation: Automatic constant voltage/current switching, soft-start delay to avoid voltage overshoot, preset voltage/current output and contactless switch output.
Overvoltage Protection: 0-120% rated voltage adjustable protection value; trips when output voltage exceeds the set value.
Short Circuit Protection: Adjustable DC power supply supports prolonged short circuits or short-circuit startup under any working condition.

FAQ

Q1: What research and development applications require a 0–100V high-voltage DC power supply?

The 0–100V high-voltage variable DC power supply is commonly used in power electronics R&D, component breakdown voltage testing, high-power communication equipment, specialized industrial machinery, and high-voltage load aging tests. It provides a higher output voltage range for testing devices that require medium-to-high DC voltage for proper operation.

Q2: Why are overvoltage and overcurrent protection essential for high-voltage models?

High-voltage output increases the risk of equipment damage and personal safety hazards if parameters exceed limits. Built-in overvoltage and overcurrent protection automatically cut off or limit output when abnormal conditions occur, protecting both the power supply and the connected devices from irreversible damage.
