Test Connections
1.
Connect the LED Load to J2 through the ammeter shown in Figure 2. Caution: Observe
the correct polarity or the load may be damaged.
2. Connect the AC power card to J1 and connect the other end to the AC wattmeter shown
in Figure 12.
3. Connect a Switch between J3-6 and J3-7. This switch will provide on/off control. If not
using a switch, short J3-6 to J3-7.
4. Short J3-4 to J3-7. This replaces the external TCO.
5. Connect a 1-10 VDC source to J3-2 and J3-7. The positive will go into J3-2 and the
negative into J3-7. This will be used for the dimming function of the board.
6. Connect the DC voltmeter as shown in Figure 2.

Note: Unless otherwise specified, all voltage measurements are taken at the terminals of the UUT.
Functional Test Procedure
1. Note: If using an on-off switch, it should be in the open state until instructed otherwise.
2. Set the LED Load for 60V output.
3. Set the input power to 120 V 60 Hz. Caution: Do not touch the ECA once it is energized
because there are hazardous voltages present.
4. Close the On/off switch if present.
5. Set the 1-10 VDC source to between 1 and 10 VDC and turn it on.
6. Repeat procedure for additional loads and input voltages for below tables.
