Utilizing primary switched-mode technology, it maintains a small form factor of 200 x 90 x 215 mm while delivering 450W of power. The unit features dual output capabilities, offering a full rated current range of 0-30A via the rear terminals and a front-panel output current limited to 5A. Users can operate the device in four distinct modes: Normal, Preset, Remote Control, and Set. It includes three user-definable presets for voltage and current, as well as remote controllability for voltage, current, and output state via external DC signals. Integrated safety features provide comprehensive protection, including overload, overheating, and current limiting, ensuring reliable performance in professional environments.
The VOLTCRAFT HPS-11530 is a compact, high-efficiency 450W bench power supply engineered for electronics engineers and laboratory technicians who require precise, reliable power in a space-saving footprint. It offers dual-output versatility and sophisticated remote control capabilities, making it ideal for testing high-current loads and sensitive circuitry; however, users should note that full 30A current output is restricted to the rear-mounted terminals, necessitating specific cable management for high-load applications.

Extended Product Information
FAQs
Can I use both front and rear outputs at the same time?
The HPS-11530 is designed to deliver power through either the front or rear terminals. It is recommended to use one at a time based on your current requirements.
How do I save settings to the presets?
Adjust the voltage and current to your desired levels in 'Set' mode, then follow the instructions in the manual to store these parameters into one of the three available memory slots.
What is the maximum output voltage?
The power supply provides a variable DC output range of 1V to 15V.
Is this unit fan-cooled?
Yes, it uses an integrated cooling system to manage heat dissipation, which is critical given its 450W power output in a compact housing.
Can the power supply be controlled by a PC?
The unit supports remote control via external DC signals, which can be provided by various control devices including PLC or PC-based data acquisition cards with analog outputs.
Troubleshooting
Output voltage drops under load
Ensure that the cables being used are of sufficient gauge for the current being drawn and verify that the rear terminals are used for loads exceeding 5A.
Unit enters thermal protection mode
Check for airflow obstructions around the device, ensure the ambient temperature is within the recommended operating range, and allow the unit to cool before resetting.
Remote control signals are ignored
Confirm that the device is specifically set to 'Remote Control' mode and that the signal polarity and voltage level of the external DC signal match the device specifications.
Pros and Cons
Pros
High power-to-size ratio saves valuable workbench space
Maximum 30A current output is only available via rear terminals
Requires external DC signals for remote control configuration
Compact form factor may lead to warmer operation under sustained maximum load
Setup, Compatibility & Care
Installation: Place the unit on a flat, stable surface ensuring at least 5cm of clearance around the ventilation intake and exhaust to prevent overheating.
Connection: For applications exceeding 5A, always use the rear terminals with heavy-gauge cabling appropriate for the 30A load to minimize voltage drop.
Modes: Select the operating mode (Normal/Preset/Remote/Set) via the front panel before connecting sensitive loads to ensure the output remains within intended parameters.
Calibration: Periodically verify output accuracy with a high-precision digital multimeter, especially after long periods of heavy use.
Cleaning: Wipe the exterior casing with a dry, soft cloth. Never use solvents or abrasive cleaners, as these may damage the control interface or front-panel display.
