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.
