Haikawa Episode 1_Regulated DC Power Supply & Battery Comparison
| | Battery | AC/DC Power Supply |
|---|
| Output Settings | Fixed | Wide range from 0 to maximum rating |
|---|
| Output Mode | Constant Voltage | Constant Voltage / Constant Current |
|---|
| Continuous Operation | Depends on battery capacity | Unlimited |
|---|
| Output Stability | Output decreases over time | Maintains constant output |
|---|
| External Control | Not supported | Supported |
|---|
| Overvoltage, Overcurrent Protection | Not supported (Possible with external circuit) | Supported |
|---|
| Capacity Expansion | Available with parallel connection | Available with parallel connection |
|---|
| Rush Current Capability | Supports instantaneous swells in current up to several times the rating | Generally not supported (Available in some products) |
|---|
| Cost | Low unit cost but is a consumable requiring continuous purchases | Start-up costs are high but only maintenance costs are electric utility expenses (not including possible repairs, calibration, etc.) |
