Peak Power and Remote ON/OFF Control

The MEAN WELL NSP-150 Series provides built-in peak power capability and remote ON/OFF control functions for industrial system integration and dynamic load applications.

For NSP-150-12, NSP-150-15, NSP-150-24, NSP-150-27, NSP-150-36, NSP-150-48 and NSP-150-60 models, the series supports up to 200% peak power capability for 5 seconds, allowing stable operation under transient load conditions such as motor startup, capacitive loads and system inrush current.

The built-in remote ON/OFF control function allows external switching of the power supply, making the NSP-150 Series suitable for systems requiring power sequencing, standby control and centralized power management.

Peak Power Capability

The NSP-150 Series supports short-term peak output for 12V to 60V models. For example, NSP-150-24 can deliver up to 300W peak power for 5 seconds, while maintaining rated output power under continuous operation.

This feature is particularly useful for applications with transient load demands such as industrial automation systems, telecom infrastructure, security equipment, network devices and other DC-powered systems requiring short-duration high current support.

Remote ON/OFF Control

The remote ON/OFF function is controlled via RC+ and RC- terminals on the CN1 connector. According to the function specification, the power supply remains ON when RC+ to RC- is open or maintained at 0–0.8Vdc.

The output is turned OFF when RC+ to RC- is driven to 3.3–10Vdc by an external control signal. This enables integration with system-level control logic, automation sequences and standby power management.

Control Connector Information

The NSP-150 Series uses a dedicated CN1 interface with RC+ and RC- pins for remote control functions. This simplifies integration into industrial equipment, automation systems, communication devices and distributed power architectures.
