TDK 3000W Programmable AC-DC Power Supply

# Official Name

TDK-Lambda HWS3000G-48

Full Name: 3000W Programmable AC-DC Power Supply (Single-phase Input, 48V Output)

Common Name: Industrial 3kW 48V Programmable Power Supply / High-power Programmable DC Power Supply

## II. Core Functions

This is a high-power power supply converting AC to regulated DC with adjustable voltage and current.

- Power Conversion: Converts 85–265VAC mains to 48V / 62.6A / 3000W DC to deliver stable high-power DC to equipment.

- Programmability: Continuously adjustable voltage 38.4–52.8V, current 0–62.6A (CV/CC constant voltage / constant current mode). Controlled via **RS485 (Modbus)** or analog signals.

- Capacity Expansion: Up to 10 units in parallel and 3 units in series to meet higher voltage or current requirements.

- Protection: Overvoltage, overcurrent, overtemperature and short-circuit protection, remote on/off control.

## III. Typical Applications

Targeting high-reliability, high-power scenarios in industry, semiconductors and test & measurement:

- Semiconductor Equipment: Power supply for wafer processing, lithography and etching machines.

- Laser Processing: Power supply for laser cutting, welding and marking machines.

- RF / Communications: Power supply for RF amplifiers, base stations and test instruments.

- Industrial Automation: Large servos, robots and production line equipment.

- Test & Measurement: Battery test, electronic load and burn-in test systems.

- Others: Medical devices (subject to certification), charging piles, auxiliary power for energy storage systems.
