NICE-POWER DC Power Supply Variable 30V 30A 900W High Power Bench Power Supply with Encoder Knob and Output Switch Lab Power Supply Adjustable Switching Regulated Power Supply for Engineer/R&D Staff

NICE-POWER R-SPS High-Power Series DC Power Supply is specifically designed for laboratories, educational institutions, and production lines. Output voltage and current can be continuously adjusted within the range from 0 to the rated value. This Bench power supply features excellent stability and an extremely low ripple coefficient. High-Current Output: This Lab power supply supports 0-30A output current. The front panel only supports output currents below 5A. For 5-30A output, connect to the high-current port on the rear panel to prevent power supply damage. Output Switch: Pressing the power button delivers the adjusted voltage and current, preventing load damage for safer, more reliable operation. High-Precision Encoder Knob: Replacing potentiometer switches, this knob switches digits with a press and sets values from 0 to 9 via rotation. Operation is easier and more efficient. Auto Constant Current/Constant Voltage Mode: This dc power supply variable delivers high-power continuous output and supports extended full-load operation. Automatic switching between constant voltage and constant current modes. Voltage/Current/Power Display: As a professional power regulation unit, the 30V 30A DC power supply offers 0.01V/0.001A high resolution. Voltage, current, and power values are displayed in real-time, eliminating the need for separate power calculations. Four-Digit LED Display: The backlit four-digit LED display on the desktop power supply accurately shows voltage, current, and power values, remaining clearly visible even in low-light conditions. Multiple Protections for Reliable Safety: The DC power supply incorporates built-in overvoltage protection, overcurrent protection, overheat protection, and short-circuit protection. Intelligent cooling fan: The fan activates automatically when operating temperature exceeds 122°F/50°C, ensuring efficient heat dissipation and extending device lifespan. CE & FCC certified: All laboratory power supplies are certified to CE and FCC standards. Wide Range of Applications: Suitable for battery charging (Lithium Iron Phosphate/Lead Acid, etc.), high-power motor testing, low-voltage aging tests, educational training, electronic device repair, home appliance maintenance, electrolysis, electroplating, LED testing, communication testing, DIY projects, and laboratory research. Ideal for users requiring high-power power supplies, such as production line and quality control engineers, power electronics and power management professionals, and DIY enthusiasts. Compact Design · Quality Assurance: Measuring just 10.2 *7.2*3.1 inch and weighing only 6.1 lbs, this desktop power supply saves workspace and facilitates portability. Package Contents: 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 policy. Lithium Battery Charging Reminder: Connect the DC power supply's positive and negative terminals to the battery's corresponding terminals. Disconnect the battery promptly when charging current ≤50mA to prevent overcharging. Charging voltage limit follows this formula: Charging voltage = 1.2 × Battery rated voltage Charging current = 1/3 × Battery rated current Important Notes: Due to power supply design limitations, the front panel is only suitable for output currents below 5A. For output currents exceeding 5A, connect to the high-current port on the rear panel to prevent damage to the power supply. The rear panel can deliver the maximum current specified in the purchased model: For example, when purchasing a 30V 30A model, connecting to the rear panel's high-current terminals enables 30A output.
