Laboratory power supply R-SPS3010 30V 10A is a compact pulsed regulated DC power supply for electronics repair, equipment testing, laboratory research and amateur radio work. The power supply allows you to adjust the output voltage from 0 to 30 V and set current limits from 0 to 10 A, providing maximum output power up to 300 W.
R-SPS3010 supports two main operating modes: voltage stabilization CV (Constant Voltage) and current stabilization CC (Constant Current) with automatic switching depending on the load. The front panel features a digital LED display for monitoring output parameters, and an additional 5V 2A USB output allows you to power compatible USB devices.
⚡ Adjustable voltage 0–30V and current 0–10A
The 30V 10A laboratory power supply allows you to adjust the output parameters according to the requirements of the connected equipment. The voltage adjustment range is 0–30 V, and the current is 0–10 A.
The maximum power of up to 300 W makes the R-SPS3010 switching power supply suitable for testing electronic modules, powering various DC devices, testing electrical circuits and performing repair work.
The voltage adjustment resolution is 0.1 V, and the current is 0.01 A, which allows you to select the necessary power supply parameters.
🔄 CV and CC stabilization modes
The R-SPS3010 regulated power supply supports automatic switching between two modes:
- CV (Constant Voltage) — voltage stabilization. The unit maintains the set output voltage until the load current exceeds the specified limit.
- CC (Constant Current) — current stabilization. When the set current limit is reached, the unit automatically reduces the output voltage, maintaining the specified current.
The presence of CV/CC modes is especially useful when checking electronic components, testing devices after repair, and working with equipment for which it is important to limit the current consumption.
🔌 Additional USB output 5 V 2 A
The front panel of the laboratory power supply provides a USB port with a fixed output voltage of 5 V and a current of up to 2 A.
The USB output can be used to power compatible electronic devices, small modules, and accessories that operate on a standard voltage of 5 V.
Important: The USB port has a fixed voltage of 5 V and is not designed to regulate the voltage in the range of 0–30 In.
📟 Digital display of voltage, current and power
The R-SPS3010 power supply is equipped with a digital LED display that allows you to monitor the main electrical parameters during operation.
The display shows:
- Voltage (V) — output voltage in volts.
- Current (A) — output current in amperes.
- Power (W) — electrical load power in watts.
Digital display of parameters simplifies setting up the power source and monitoring the power consumption of connected equipment.
🌬️ Active cooling with temperature control
Switched laboratory power supply R-SPS3010 The 300Wis equipped with a temperature-controlled fan. The cooling system helps dissipate heat from internal components while operating under load.
Thermal fan control helps reduce noise and maintain proper thermal conditions for the power supply.
