HEC-40LTA-XXPSAF Rev A
Notes:
1. Normal input voltage range 100~240Vac.
2. Measured at input 220V with a full load.
3. All specifications are typical at 25 °C unless otherwise stated.
4. Constant current operation region is preferably 80%~100% rated output voltage. This is the suitable operation region for LED related applications, but
please reconfirm special electrical requirements for some specific system design.
5. Derating may be needed under low input voltages. Please check the static curve for more details.
6. The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by
the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again
E. Dimming Control
The dimmer control is operated from an input signal (DC voltage / PWM signal / Variable Resistor). Please refer to the
diagram.
Notes:
1. If the dimming pin is not used, Dimming pin can be open.
