Pros & Cons
Pros
- ✓ Jumper-selectable input handles 95-132V ac or 190-264V ac on 50-60 Hz single-phase
- ✓ Tight +/-1.0% voltage regulation with 0.05% per deg C thermal drift
- ✓ Continuous 4 A dc output with 6 A intermittent headroom for 10 seconds
Cons
- ✗ Generic replacement, not a Cummins-branded OEM part
- ✗ Needs 15 ohms minimum field resistance, so check your exciter first
- ✗ Max 90V dc output only at 207V ac input, lower input cuts the ceiling
- ✗ Jumper must be set correctly for your voltage range before first start
