Is this a DIN Rail Mounted Dimmable LED Driver
ADM stocks the MEAN WELL DRA series DIN rail power supplies.
Like many of MEAN WELL’s constant voltage LED drivers, these DIN rail power supplies can be used in constant current mode.
There are 4 models within the range:
|
Part Number |
Ouput Voltage |
Max Current |
Constant Current Region |
|---|---|---|---|
| DRA-40-12 | 12 ~ 15V | 3.34A | 3 ~ 12V |
| DRA-40-24 | 24 ~ 30V | 1.7A | 3 ~ 24V |
| DRA-60-12 | 12 ~ 15V | 5A | 3 ~ 12V |
| DRA-60-24 | 24 ~ 30V | 2.5A | 3 ~ 24V |
The output voltage can be adjusted using the built-in potentiometer, which is easily accessed from the front of the power supply.
The constant current level can be programmed dynamically by three methods: 1-10V input signal, 10V PWM signal, or by a 100Kohm potentiometer. This means these power supplies could be used to power LEDs and will dim the lights if the current level is reduced by using one of these 3 methods.
Simply put, the DRA series power supplies behave in the same way as most of MEAN WELL’s dimmable LED drivers with 3-in-1 dimming.
These power supplies are perfect for powering constant current light fittings from an electrical enclosure in industrial environments.
So long as the output voltage is within the specified constant current region, the output current level can be set anywhere from 10% to 100%. This enables you to power a vast range of constant current light fittings from one power supply.
One thing to note. These power supplies do not carry the AS/NZS 61347-1, which is a requirement for LED drivers in Australia. These power supplies carry the approvals for DIN rail power supplies instead.
