Frequently Asked Questions
Can I use the PWM-120-12 to power 12V LED strip lighting in an outdoor sign cabinet?
Yes. The PWM-120-12 is rated IP67, meaning it is dust-tight and protected against temporary immersion, making it suitable for installation inside outdoor sign cabinets exposed to rain and humidity. It delivers 12V at up to 10A (120W total) and operates from -40°C to +90°C.
Is the PWM-120-12 suitable for powering 12V LED strips in a covered outdoor pergola or soffit?
Yes. Its IP67 rating protects against water jets and temporary immersion, so a covered outdoor location with indirect moisture exposure is well within its rating. The operating temperature range of -40°C to +90°C also covers extreme outdoor conditions.
What dimming methods does the PWM-120-12 support?
The PWM-120-12 includes built-in 3-in-1 dimming, which means it accepts PWM signal, 0-10V analog, and resistance dimming inputs without any additional adapter or gateway. This makes it compatible with a wide range of common dimmer controllers used in LED lighting systems.
How many meters of 12V LED strip can the PWM-120-12 drive?
The PWM-120-12 provides a maximum of 120W at 12V. To estimate strip length, divide 120W by your strip's rated wattage per meter — for example, a 14.4W/m strip supports up to approximately 8.3 meters (120 ÷ 14.4). Always check your specific strip's rated power per meter and apply a 20% derating margin for best practice.
Can I use the PWM-120-12 for retail display case lighting that requires smooth dimming?
Yes. The PWM-120-12 uses a PWM-style output that is specifically designed for smooth, flicker-free dimming of 12V LED strips and modules. The built-in 3-in-1 dimming interface allows compatibility with standard PWM, 0-10V, and resistance dimmer types used in retail lighting.
How does the PWM-120-12 differ from the PWM-120-12DA and PWM-120-12KN?
All three models deliver 120W at 12V/10A with IP67 protection. The PWM-120-12 uses built-in 3-in-1 dimming (PWM, 0-10V, resistance). The PWM-120-12DA replaces that with a DALI interface for building-automation lighting networks. The PWM-120-12KN uses a KNX interface, eliminating the need for a separate KNX-DALI gateway.
Can the PWM-120-12 be installed in an unheated warehouse or cold-storage area?
Yes. The PWM-120-12 is rated for operating temperatures from -40°C to +90°C, so it will operate normally in unheated or cold-storage environments without derating.
