About This Item
2023 Upgrade High-Precision Encoder Knob
- Just "set" voltage and current instead of "adjust". The encoder switch replaces the potentiometer switch. Digits are switched by pressing the knob, and each digit can be set in the range of 0-9 by turning the knob, making work easier and more efficient!
Stable Output, Auto Switch C.C/C.V Mode
- This variable DC power supply is a low noise, low ripple adjustable high-power continuous output power supply that can work at full load for long periods. Constant voltage and constant current modes switch automatically.
4-Digit LED Display, Power Display
- The 30V 30A DC power supply is a professional power conditioning unit with a high resolution of 0.01V and 0.001A. The backlit 4-digit LED display shows voltage, current, and power values more accurately, and is easy to see even in low light conditions.
Multiple Protection, Intelligent Cooling Fan, Reliable and Safe
- The DC power supply features built-in overvoltage, overcurrent, overheating, and termination protection. When the operating temperature exceeds 122°F/50°C, the fan turns on to dissipate heat effectively, extending the device's life. Shock-absorbing rubber feet at the bottom ensure safer and more stable use.
CE & FCC Certification, Widely Used
- The 30V 30A lab power supply is CE and FCC certified. Suitable for labs, schools, electronic repair, battery charging, electrolysis, electroplating, lamp testing, aging testing, DIY projects, research, and teaching.
Compact Design, Quality Check
- Measuring only 382413 cm and weighing only 3 kg, it saves bench space and is easy to carry. Delivery includes: DC power supply *1; power cord *1; English manual; low-power output cable *1; high-power output cable *1. We offer a 12-month warranty. For any questions, please contact us and we will reply within 24 hours.

NICE-POWER R-SPS High Power Bench DC Power Supply
NICE-POWER R-SPS high power series DC power supplies are designed for use in laboratories, schools, and production lines. Output voltage and current can be continuously adjusted between 0 and nominal values. The stability and ripple coefficient are excellent. With short-circuit protection, over-voltage protection, over-current protection, and over-temperature protection, it can work at full load for long periods. It can be used as both a regulated voltage and a regulated current power supply, favored by many users.
Please note: The front is suitable for output currents below 5A. For output currents above 5A, please connect the high current connector on the back to avoid damage to the power supply.
Stable Output
- Easily adjust the required voltage and current, automatically calculating the output power according to the voltage and current. High accuracy of 0.01V and 0.001A.
Intelligent Fan
- The intelligent fan turns on when the temperature exceeds 50°C, effectively dissipating heat.
4-Digit LED Display
- Provides more accurate and clearly visible readings of voltage, current, and power values.
Warning
- Due to an adjustment delay, turn on the DC power supply first, set the voltage/current, then connect the load.
- When setting the current, adjust the voltage below 3V first to avoid sparks, then connect the positive and negative output wires, and set the desired current.
- Turn off the DC power supply when not in use, and remove the power cord.
- When cleaning, ensure the power cord is removed.
- Avoid using solvents containing hydrocarbons, chlorides, or similar, and detergents with abrasive ingredients.
- The voltage will gradually decrease when you turn off the power as the capacitor releases the voltage.
Questions & Answers
Q1: The current knob has been turned; why can't the current be adjusted?
- A1: You must connect a load, and the voltage setting cannot be 0. Then adjust the current.
Q2: Why isn't the cooling fan working?
- A2: The smart cooling fan has a built-in temperature control sensor that activates at 50°C.
Q3: How do I choose the input voltage (220V or 110V) and the plug type (EU/AU/US/UK)?
- A3: We send the corresponding products and plug according to your country. For special needs, please contact us.
Q4: Scratches on the screen?
- A4: There is a protective film on the screen that can be peeled off.
