■ 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.

DIMMING OPERATION
The PWM style output is a simple switching of supply ON/OFF at a rate so fast that the human eye cannot see LED
flickering. 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-.

◎Cautions
Before commencing any installation or maintenance work, please disconnect the power supply from the utility. 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.
