|Electrical hardware mounted on a cutting board. Samlex SEC-1230UL 30-A charger, Optima Blue Top 55-Ah battery.|
- The SEC-1230UL is a switch mode supply but quiet enough to not interfere with HF reception.
- With the SEC-1230UL and a battery, the system behaves as a dc Uninterruptible Power Supply.
- With 120 Vac available, the system can maintain a <30 A draw indefinitely (limited by the charger). However, higher amperages can be sustained intermittently (limited by the battery).
