||
| 3. 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 manufactures must be-qualify EMC Directive on the complete installation agai | ||
| 4. To extend the driver's using life , please reduce the loading at lower input voltage . | ||
MCB recommendation
| When the input voltage is 120Vac,the number of LED Driver matched by circuit breakers is as follows: | ||
| MCB Type | Level | The number of LED Driver |
| C type(breaking capacity:6KA) |
10A | 20 |
| 13A | 26 | |
| 16A | 32 | |
| 20A | 40 | |
| 25A | 50 | |
| When the input voltage is 230Vac,the number of LED Driver matched by circuit breakers is as follows: | ||
| MCB Type | Level | The number of LED Driver |
| C type(breaking capacity:6KA) |
10A | 27 |
| 13A | 35 | |
| 16A | 44 | |
| 20A | 55 | |
| 25A | 69 | |
| When the input voltage is 277Vac,the number of LED Driver matched by circuit breakers is as follows: | ||
| MCB Type | Level | The number of LED Driver |
| C type(breaking capacity:6KA) |
10A | 40 |

Dimming Operation and Connecting Diagram:
DALI bus on


Note:
1. When Turn on the internal DALI bus power.No need external bus power supply.
2. The model name SMT-DI020W070-D4IA means that there is no auxiliary power supply and temperature control, so there is no corresponding wiring for the LED driver.
3. The model name SMT-DI020W070-D4IA-Y means that there is an auxiliary power supply but no temperature control, so the LED driver has no temperature control wiring.
4. The model name SMT-DI020W070-D4IA-T means that there is no auxiliary power supply but there is temperature control, so the LED driver has no auxiliary power wiring.
5. The model name SMT-DI020W070-D4IA-YT means that there is an auxiliary power supply and temperature control.
NFC function
Adjust output current slightly by NFC
The output current can be read and written by a mobile with ProNFC APP or NFC handheld device (NFC read & write device: NFC-RW) by close to the NFC signal area of the Dimmable LED driver.
Set Address easily by NFC
The address can be read and written by a mobile with Set NFC APP or NFC handheld device (NFC read & write device: NFC-RW) by close to the NFC signal area of the Dimmable LED driver.
