Developing an audio amplifier prototype often involves powering multiple circuit sections, such as amplifier stages, driver circuits, and supporting electronic components. The NICE-POWER SPS305-2KD features two independently adjustable DC output channels, each delivering 0–30V, 0–5A, and up to 150W.
This dual-channel bench DC supply allows users to power two separate circuits from one unit, making it more convenient to configure different supply requirements during amplifier circuit development, prototype assembly, and initial power-up testing.
Audio amplifier circuits and their supporting components may require different DC supply configurations during development. The SPS305-2KD provides independent, series, and parallel output modes to accommodate different power requirements.
With one-key series and parallel switching, users can change the output configuration without complicated external wiring. Series mode provides up to 60V at 5A, while parallel mode provides up to 30V at 10A. A dedicated series-parallel output port makes switching between these configurations more convenient.
When bringing up an amplifier prototype, engineers need to set the supply voltage and current according to the circuit's requirements and monitor the output during operation. The SPS305-2KD uses encoder adjustment for convenient parameter setting and provides four-digit voltage, current, and power displays.
Its CV/CC indicators show the constant voltage or constant current operating state, helping users observe the power supply's output condition while adjusting and testing amplifier circuits.
Some amplifier circuit designs use positive and negative supply rails for their electronic stages. The SPS305-2KD supports negative voltage–zero voltage–positive voltage output mode, providing additional flexibility for prototype development involving different voltage polarities.
This capability is useful when working with amplifier-related electronic circuits that require different supply polarities, subject to the output configuration and electrical requirements of the circuit.
In addition to its two adjustable DC output channels, the SPS305-2KD includes a dedicated USB 5V/2A power output. It provides a convenient auxiliary power source for compatible USB-powered devices used at the electronics workbench, without taking up either adjustable DC output channel.
Suitable for powering audio amplifier prototypes during circuit assembly and development. The two independent output channels allow users to supply power to separate circuit sections, making it easier to configure and evaluate amplifier-related electronic circuits during the development process.
Useful for supplying adjustable DC power to pre-amplifier and driver-stage circuits. Users can set the output voltage and current according to the circuit's requirements, helping with initial power-up, circuit troubleshooting, and prototype evaluation.
For amplifier-related designs that require different voltage polarities, the negative–zero–positive voltage output capability offers additional supply configuration flexibility. It can support development work involving circuits with positive or negative supply requirements, within the power supply's specified output limits.
When developing an amplifier together with its supporting electronic circuits, two independently adjustable outputs provide a convenient way to power separate circuit sections. Series and parallel modes also offer alternative output configurations when a higher voltage or current capacity is required.
