2000W Adjustable DC Switching Power Supply
The 2000W adjustable DC switching power supply covers a broad voltage range from 24V to 600V, enabling precise control for demanding test rigs and high-voltage experiments. Its high-precision four-digit LED display makes monitoring voltage and current straightforward, supporting accurate regulation during lab work. This model is suitable for bench setups requiring a stable supply with wide headroom, and its robust build supports sustained operation in research and development environments.
NICE-POWER DC Power Supply Variable, 0-400V
This NICE-POWER model offers a 0-400V adjustable output with four memory storage slots (M1–M4), allowing quick recall of commonly used voltage-current values. The encoder knob enables fast, precise tuning, and the LOCK button prevents accidental re-adjustment. A color 4-digit display provides clear readouts with high resolution for voltage and current, making it ideal for repeated voltage profiles in testing and calibration tasks.
NICE-POWER DC Power Supply Variable, 300V 1A
This variable power supply supports programmable control via RS232/USB ports with optional Windows software. It enables precise voltage/current adjustments, multi-value memory storage, and data export for graphs and tables. The encoder knob, output switch, and lock button contribute to reliable operation in lab settings, while PC software adds a programmable interface for automated experiments.
DC Power Supply Variable, 60V 5A
With a maximum of 60V and 5A, this power supply emphasizes precision via a four-digit LED display offering 10mV and 1mA resolution. It includes multiple protections such as over-voltage and short-circuit safeguards, plus a cooling fan for temperature control. A USB-C charging port (5V/2A) adds versatility for charging devices during testing or maintenance tasks.
VAYALT DC 12V 50A Switching Power Supply
The VAYALT switching supply delivers 12V at up to 50A (600W peak). It supports 110V/220V AC input and includes a heat sink and cooling fan to manage heat during high-load operation. This unit is suitable for CCTV, LED lighting, and hobbyist electronics projects requiring a compact, high-current 12V source with reliable thermal management.
Buying Guide: Key Considerations for 500V DC Power Supplies
- Voltage range and headroom: Choose a unit that covers your target voltage with some margin (e.g., up to 600V) to accommodate startup surges and transient loads.
- Current capability: Ensure the supply can deliver the required current at the highest voltage without overheating or triggering protection limits.
- Regulation and display: Four-digit or higher resolution displays improve monitoring accuracy. Look for fine control via encoder knobs for precise adjustments.
- Memory storage: Memory presets speed repetitive testing. Four or more memory slots are common and helpful for quickly switching configurations.
- Protection features: Over-voltage, over-current, short-circuit, and over-temperature protections safeguard both the power supply and the tested devices.
- Control interface: USB/RS232 or PC software enables automated control, logging, and integration into test benches or automation pipelines.
- Safety and build quality: Thermal management, robust enclosures, and secure input/output terminals reduce risk in high-voltage setups.
- USB charging and auxiliary ports: Some units include USB outputs (5V/2A) for charging devices, which can be useful during lab sessions.
- Cooling and noise: Internal fans and heatsinks extend service life but may introduce noise; position the unit with adequate ventilation.
- Compatibility with loads: Consider the load type (resistive, capacitive, inductive) and ensure the supply can handle startup and steady-state requirements for those loads.
