The EV4001-S-00A can supply a maximum
output current of 350mA to drive 10V-to-30V
LED strings from an input voltage of 90VAC to
265VAC at 50Hz/60Hz.
Applying a pulse width modulated square wave
signal between the DIM and GND pins
implements PWM dimming.
The EV4001-S-00A meets EN55015 EMI
standards. The EVB fits in PAR-22 lighting
fixtures.

QUICK START GUIDE
1. Connect the LED string between “LED_P” (anode of LED string) and “LED_N“ (cathode of LED
string).
2. Connect the AC input voltage between “N” and “L” the AC input terminals as shown on the board.
3. Turn Power Supply off.
4. Preset AC Power Supply to 90V  AC input  265V.
5. Turn Power Supply on after making connections.
PWM Dimming
The EV4001-S-00A can use PWM dimmed by applying a square TTL-compatible signal between DIM
and GND terminals. Since there is no galvanic isolation on the board, care must be taken to prevent
damage to the PWM dimming source.
Suggested use of an opto-isolation to drive the DIM pin. Reference figure shown below.
