Selection Notes

The 6EP3437-8UB00-0AY0 is the 24 V/30-40 A member of the PSU3800 charging family, sized for 24 V battery banks where the 12 V/20 A model in the same series would be undersized. The constant-current fallback under short circuit (approx. 44 A) and minimal switch-on overshoot (under 3%) are the traits that make this a charging-rated supply rather than a general-purpose 24 V rail; a standard PSU8600 or PSU8200 unit is not rated for repeated deep-discharge recharge cycles the way this PSU3800 model is. Pick the 12 V/20 A PSU3800 sibling instead for 12 V battery systems; the buffer module accessory listed for this device can be added to bridge short mains interruptions independently of the battery under charge.
