NICE-POWER 500W Variable DC Power Supply, 100V 5A Adjustable Switching Regulated Bench Power Supply with Encoder Knob - Perfect for Lab Testing, Electronics Repair, Battery Charging & DIY Projects

NICE-POWER R-SPS High Power Bench DC Power Supply NICE-POWER R-SPS high power series dc power supplies are specially designed for use in laboratories, schools and production lines, with output voltage and output current that can be continuously adjusted between 0 and nominal values. The stability and ripple coefficient of the power supply are very good. With short-circuit protection, over-voltage protection, over-current protection, over-temperature protection and other protection circuits, can work at full load for a long time, the power supply can be used as both a regulated voltage power supply and a regulated current power supply, loved by the majority of users. Warm tips for charging lithium batteries: Please connect the positive and negative poles of the DC power supply with the positive and negative poles of the battery correspondingly;When the charging current ≤ 50mA, please disconnect the battery in time to avoid overcharging;The charging limiting voltage follows the following calculation formula: Charging voltage = 1.2 * battery rated voltage. Charging current = 1/3 battery rated current. Please note: Due to the design of the power supply, the front panel is only suitable for output currents up to 5A. To avoid damaging the power supply, connect the high current connector on the back of the unit for output currents above 5A. The back panel can reach the maximum current of the purchased specification: for example, if you purchase 30V 30A, the current can reach 30A by connecting the back panel high-current terminal. Stable Output The dc power supply can easily adjust the required voltage and current, and automatically calculate the output power according to the output voltage and current. It has high accuracy of 0.01V and 0.001A. Intelligent Fan When the operating temperature of the lab power supply exceeds 122°F or 50°C, the fan will turn on intelligently to dissipate heat effectively. Reduces working noise and extends equipment life. 4-digit LED display The LED screen provides more accurate and clearly visible readings of voltage, current and power values.

【2023 Upgrade High-precision Encoder Knob】 Just "set" voltage and current instead of "adjust". The encoder switch replaces the potentiometer switch, the digits are switched by pressing the knob and each digit can be set in the range 0-9 by turning the knob. Makes 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 of time. Constant voltage and constant current modes can be switched automatically.

【 4-Digit LED Display, Power Display】 100V 5A DC Power Supply is a professional power conditioning unit with high resolution of 0.01V and 0.001A. The backlit 4-digit LED display of the bench power supply shows the 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 has built-in overvoltage protection, overcurrent protection, overheating protection and termination protection. When the operating temperature of the DC power supply exceeds 122°F/50°C, the fan will turn on intelligently to dissipate heat effectively and extend the life of the device. DC power supply has shock absorbing rubber feet at the bottom for safer and more stable use.

【CE & FCC Certification, Widely Used】 100v 5a Lab power supplies have passed CE & FCC Certification. This benchtop power supply is suitable for battery charging ( LiFePO4, lead acid batteries, etc.), labs, schools, electronics repair, electrolysis, electroplating, lamp testing, aging testing, DIY, research and teaching.
