Output voltage adjustment range by Model VTRM terminal [V] 1.3 Overcurrent Protection HCA3500TF-48 24.0 to 55.2 HCA3500TF-65 32.5 to 74.7 ¡ A unit has the built-in overcurrent protection circuit which will acti- * The output voltage should not be adjusted to lower voltage than vate at over 105% of the rated current.
If the output voltage becomes unstable, we suggest you to try to connect C1, C2, C3, R1, R2 and R3. 6If the output voltage is unstable because the sensing line is long, adjust R1 and R2. Please contact us for details. HCA-9 www.cosel.co.jp/en/ April 04, 2024...
