Notes:
1) Where measurement conditions have not been specified precisely, the conditions used were ambient temperature +20 ℃ +68 ℉.
2) The power supply connected to this product must satisfy the following conditions:
1 SELV (Safety Extra Low Voltage):
Reinforced insulated from hazardous potential part (48 V or more)
2 Compliance with the LVD (Low Voltage Directive)
3 Output voltage within 21.6 V to 26.4 V DC (Ripple P-P: 10 % or less.)
3) Total number of input points is 8 points, and use 2 points for control output (OSSD 1, 2) of 2 light cutains. Two inputs terminals are assigned for each input since dual wiring is supported.
