Yes, PWM is just switching on and off really fast. Seller recommends 1khz switching frequency. The output power is fixed but can be adjusted via a different resistor or add a trimpot. If you wanted to get fancy you could also use and I2C trimpot and a little code work in marlin to set the output power with g-code.
