Product Information
Full details
The Voltcraft LPS1305 is an electronically stabilized laboratory power supply designed for electronics professionals and hobbyists requiring a reliable DC voltage source for low-voltage consumers. Its key benefit lies in the precise, independent adjustment of voltage and current, alongside high-contrast LED displays for accurate monitoring, offering flexibility for various testing and development tasks. A potential caveat is that it requires careful setting of coarse and fine controls for optimal voltage adjustment, which may have a slight learning curve for new users.

FAQs
What is the maximum power output of the LPS1305?
The Voltcraft LPS1305 has a maximum power output of 150W, achieved through its adjustable voltage (0-30V) and current (0-5A) limits.
Can I preset the current limit without a jumper?
Yes, the current limit can be independently adjusted using the dedicated current control knob without the need for any jumpers.
How do I achieve precise voltage settings?
The LPS1305 features both coarse and fine control knobs for voltage. Use the coarse control for a quick initial setting and the fine control for precise adjustments to reach the exact voltage required.
What type of connectors does the LPS1305 use?
The device uses standard 4mm safety sockets on the front panel for connecting your low-voltage consumers.
Is the LPS1305 suitable for sensitive electronic components?
Yes, as an electronically stabilized power supply, it provides a stable and regulated DC voltage source, making it suitable for sensitive electronic applications.
Does the power supply have protection against short circuits?
Yes, the LPS1305 is equipped with overload and short-circuit protection to safeguard both the unit and the connected load.
How is the unit cooled?
The LPS1305 features an active cooling system to ensure consistent performance and longevity, especially during prolonged or demanding operations.
Troubleshooting
Device does not power on.
Check that the power cord is securely connected to both the unit and a working AC outlet. Verify the mains voltage is within the device's operating range. Ensure the power switch is in the 'ON' position.
LED displays show no reading or erratic values.
Ensure the load is properly connected to the output terminals. Check for loose connections. If the issue persists, contact customer support.
Output voltage is unstable or drops significantly under load.
Verify that the load's current draw does not exceed the preset current limit. Ensure the load's power requirement is within the PSU's capability (30V/5A). Check for loose connections at the output terminals.
Device shuts down unexpectedly.
The unit may have overheated or gone into overload/short-circuit protection. Allow the device to cool down. Check the connected load for short circuits or excessive current draw. Reduce the load or current limit and try again.
Pros and Cons
Pros
- Precise independent control over voltage and current.
- Clear and accurate readings via dual LED displays.
- Adjustable current limiting for device protection.
- Robust overload and short-circuit protection.
- Active cooling system for sustained operation.
- Easy connection via standard 4mm safety sockets.
Cons
- Coarse and fine voltage control may require a slight adjustment period.
- User interface relies on physical knobs, lacking digital presets.
- No inherent memory function for saving settings.
Setup, Compatibility & Care
Setup:
- Ensure the power supply is placed on a stable, well-ventilated surface.
- Connect the main power cord to a suitable AC outlet.
- Use standard 4mm banana plugs or wires to connect your low-voltage consumer to the front panel safety sockets.
- Turn on the power switch. The LED displays will illuminate.
- Adjust the coarse and fine voltage control knobs to set the desired output voltage.
- Adjust the current control knob to set the maximum current limit. The device will operate in constant current (CC) mode if the load attempts to draw more current than set.
Compatibility:
This power supply is compatible with any low-voltage DC consumer requiring up to 30V and 5A. Ensure the connected device's power requirements do not exceed the LPS1305's maximum output of 150W (0-30V, 0-5A).
Care:
- Cleaning: Disconnect the power supply from the mains before cleaning. Wipe the exterior with a dry or slightly damp, lint-free cloth. Avoid using solvents or abrasive cleaners.
- Ventilation: Keep the air vents clear of dust and obstructions to ensure proper operation of the active cooling system. Periodically check and clean the vents with a soft brush or compressed air.
- Storage: Store in a dry environment when not in use.
