PWM-120 120W PWM output LED power supply F 110 ■ Features Universal AC input / Full range (up to 305VAC) Built-in active PFC function Constant voltage PWM style output Dimming range : 0~100% High efficiency up to 90.5% Protections: Short circuit / Over load / Over voltage M M SELV IP67 series 05 ■ Applications LED strip lighting Indoor LED lighting LED decorative lighting Architecture lighting / Over temperature Class Ⅱ power unit, no FG Built-in 3 in 1 dimming function (0~10Vdc or PWM signal or resistance) Suitable for dry / damp / wet locations No load power consumption<0.5W 5 years warranty ■ Description PWM-120 is one 120W waterproof constant-voltage output LED power supply series. Differentiating from general DC output power supplies, PWM-120 transmits PWM style output, adapting to directly driving all kinds of LED strips that the color temperature can be maintained and the brightness homogeneity can be assured. Adopting a universal input range between 90VAC and 305VAC and incorporating the built-in PFC function, this series is also designed with a 3 in 1 dimming function (0~10Vdc, PWM signal or resistance) that simplifies the brightness adjustment for system designers so as to achieve light reduction and energy conservation. Providing a high efficiency up to 90.5% and a low no load power consumption below 0.5W, PWM-120 can satisfy the energy saving demand for the new generation LED lighting. The class Ⅱ design (without FG pin) and the double insulation weather-resistant cable (SJTW) on the input side make it convenient for users to flexibly install on various types of lighting systems. The enclosure design is a 94V-0 flame retardant plastic case. The interior is fully potted with silicone that enhances the heat dissipation and allows PWM-120 to meet the anti-vibration demand up to 5G; it also thus conforms to IP67 level, enabling PWM-120 to be used in a highly dusty and highly humid harsh environment. The entire series can operate under the temperature between -40~+70℃ and comply with the relevant global lighting safety certification. ■ Model Encoding PWM - 120 - 12 Output voltage Output wattage Series name File Name:PWM-120-SPEC 2015-06-02 PWM-120 120W PWM output LED power supply series SPECIFICATION MODEL OUTPUT PWM-120-12 PWM-120-24 PWM-120-36 PWM-120-48 DC VOLTAGE 12V 24V 36V 48V RATED CURRENT 10A 5A 3.4A 2.5A RATED POWER 120W 120W 122.4W 120W DIMMING RANGE 0 ~ 100% PWM FREQUENCY (Typ.) 300Hz VOLTAGE TOLERANCE ±4.0% ±4.0% ±2.0% ±1.0% SETUP, RISE TIME Note.2 500ms, 80ms 230VAC / 115VAC at full load HOLD UP TIME (Typ.) 16ms/230VAC VOLTAGE RANGE 90 ~ 305VAC FREQUENCY RANGE 47 ~ 63Hz POWER FACTOR (Typ.)

Duty cycle describes the proportion of time when output voltage is ON relative to the entire period of time. It is expressed in percentage, 100% being fully ON (maximal brightness) and a low duty cycle corresponding to lower brightness. With built-in 3 in 1 dimming function, the duty of the PWM style output can be adjusted through output cable by connecting a resistance or 0~10Vdc or 10V PWM signal between DIM+ and DIM-. ◎Connection LED Strips +V -V DIM+ + + - + 0~10Vdc or 10V PWM or resistance control dimmer DIM- - ※DO NOT connect "DIM- to -V" File Name:PWM-120-SPEC 2015-06-02 PWM-120 120W PWM output LED power supply series ◎Duty cycle of output current VS Dimming input 100% when DIM+/DIM- are open circuit. 100% 90% Duty cycle of output current 80% Note 70% ※ Note : The output current drops down to 0% when the dimming input is about 6 KΩor 0.6Vdc, or 10V PWM signal with 6% duty cycle.

Ensure that it cannot be re-connected inadvertently! Keep proper ventilation around the unit and do not stack any object on it. Also a 10-15 cm clearance must be kept when the adjacent device is a heat source. Mounting orientations other than standard orientation or operate under high ambient temperature may increase the internal component temperature and will require a de-rating in output current. Current rating of an approved primary /secondary cable should be greater than or equal to that of the unit. Please refer to its specification. For LED power supplies with waterproof connectors, verify that the linkage between the unit and the lighting fixture is tight so that water cannot intrude into the system. For dimmable LED power supplies, make sure that your dimming controller is capable of driving these units.PWM series require 0.15mA each unit. Tc max. is identified on the product label. Please make sure that temperature of Tc point will not exceed limit. DO NOT connect "DIM+ to -V". Suitable for indoor use or outdoor use without direct sunlight exposure. Please avoid immerse in the water over 30 minutes. The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again.
