Hoteche DC Power Supply Variable
Product Features
Bright Led Display
Precision and accurate with 3 digit displayreaches to 100mv, 10mA that easy to read.
Accuracy Adjustment
Coarse and fine adjustments knob designed ,and easy for you to adjust your desired value.
Compact Design & Lightweight
It's designed in small size and lightweight . very easy to carry.
Intelligent Cooling Fan
The power supply adopts intelligent fan,which effectively reduces noise and extends the life of the fan.
How it works?
Widespread Application
Is the electrical noise (ripple) low enough for sensitive audio or radio repairs?
Yes! While switching power supplies are naturally more efficient and compact than linear ones, the HOTECHE 30V 5A model features advanced internal filtering to minimize output ripple and noise.
How does the "Constant Current (CC)" mode work? Will it protect my LED or circuit from burning out?
The CC mode is your primary safety feature. You can pre-set a maximum current (e.g., 20mA for an LED). If your circuit tries to pull more than that, the power supply will automatically lower the voltage to maintain that exact current limit.
What happens if I accidentally short-circuit the output leads while it's turned on?
The HOTECHE power supply is equipped with robust Short-Circuit and Overload Protection. In the event of a short, the unit will immediately enter Constant Current (CC) mode or trigger its protection circuit to limit the output.
Can this unit run at full load (30V / 5A) for several hours without overheating?
Yes, it is designed for continuous duty. It features an Intelligent Temperature-Controlled Cooling Fan that only activates when the internal heat reaches a certain threshold. This keeps the unit quiet during low-power tasks.
Is the voltage adjustment "Coarse" or "Fine"? Can I accurately set it to exactly 3.3V or 5.0V?
Our variable knobs are designed with high precision in mind. This power supply allows for smooth, incremental adjustments. You can easily dial in precise voltages like 3.3V, 5.0V, or 12.0V with confidence.
