Description
PWM-90 is one 90W waterproof constant-voltage output LED power supply series. Differentiating from
general DC output power supplies, PWM-90 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 2 in 1 dimming function (0~10Vdc or PWM signal) 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-90 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-90
to meet the anti-vibration demand up to 5G; it also thus conforms to IP67 level, enabling PWM-90 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.
Built-in 2 in 1 dimming function. The duty of the PWM style output can be adjusted through output cable by connecting
a 0~10Vdc or 10V PWM signal between DIM+ and DIM-.
