MSL2010-INR is a high efficiency LED driver programmable power supply (PPS) controller designed to deliver intelligent, precise and safe LED lighting system control. MSL2010-INR is part of a family of PPS controllers, also including MSL2010-ER and MSL2010-CVR, designed to provide a full suite of power solutions for all lighting system needs. MSL2010-INR makes it easy to design a power system that is both cost-effective and energy-efficient. It offers excellent efficiency, no-load power consumption, and fast responding. All these features make the MSL2010-INR the ideal solution for powering a wide range of LED lighting systems.

MSL2010-INR power solutions can be used for a variety of applications such as LED lighting, industrial lighting, and medical lighting. The controller is also suitable for driving high power LEDs for automotive, residential, and commercial applications. It offers a wide input voltage range from 85 to 265VAC, and can support high-current output up to 6A max. The excellent thermal performance of MSL2010-INR helps hold down heat dissipation and component stress to limit the impact of thermal cycling. This can help protect the circuit, LED drivers, LED lighting, and LED system stability.

The MSL2010-INR consists of a power circuit, an LED driver properties control circuit, an AC-DC power converter circuit, and a current flowing circuit. The power circuit can divide power into three parts with adjustable output voltage and current. It also has an over-voltage protection feature, which can stop output if the output voltage exceeds a certain amount. The LED driver properties control circuit enables the controller to adjust to match the current-voltage characteristics of different LED lamps in order to ensure the stability and reliability of LED lighting. In addition, the LED driver control circuit includes a low-voltage protection feature, which can prevent the LED from being damaged due to insufficient voltage.

The AC-DC power converter circuit of the MSL2010-INR converts the AC line to DC power. It utilizes a Pulse Width Modulation (PWM) dimming mode for controlling the output current, in order to ensure that the DC Bus Voltage is steady and can provide very stable output current in a wide RPM range. In addition, it adopts an active power factor correction technology to achieve a power factor of more than 0.95, allowing the MSL2010-INR to meet the highest efficiency standards.

The current flowing circuit of MSL2010-INR consists of a FET controller, a precision current sensing circuit, and a voltage regulator. The FET controller can adjust the switching frequency and duty cycle according the voltage level of the sensed signal. It also features overload protection, constant current regulation, and overheat protection. The precision current sensing circuit is a self-contained isolated current sensing circuit, which is used to monitor the current flowing through the LED driver. The voltage regulator is used to maintain the input voltage to a certain level, so that LED lamp maintains ave rage stability in both temperature and voltage.

Overall, MSL2010-INR is a programmable power supply controller with excellent efficiency, superior no-load power consumption, and fast responding. It provides an easy and cost-effective way to power LED lighting systems and can deliver intelligent, precise, and safe LED lighting control.
