OUTPUT VOLTAGE ADJUSTMENT

Output is adjustable for 10% trim up or -20% trim down of nominal output voltage by connecting an external resistor between the TRIM pin and

either the +SENSE or -SENSE pins. With an external resistor between the TRIM and -SENSE pin, the output voltage set decreases. With an external

between the TRIM and -SENSE pin, the output voltage set point increases. Maximum output deviation is +10% inclusive of remote sense. The

value of the external resistor can be obtained by the equations below. The external TRIM resistor needs to be at least 1/8W resistor.

NOTES

1. Models with thru-hole inserts cannot be equipped with a heatsink.

2. Terminal block models (suffix “T”, “TF”, and “TF1”) cannot be equipped with a heatsink.

3. No “SY” or “CP” functions for terminal block types.

4. Only 0.200” pin length is available with terminal block options.

5. Models with EMC filter (suffix “TF” and “TF1”) meet EN55011, EN55022 Class A.
