RS Series: Single Output (15W ~ 150W)
The RS series offers dependable single-channel DC power for general automation, instrumentation, and mechanical equipment.
| Model Group | Power Range | Available Output Voltages (DC) | Max Efficiency (Typ.) |
|---|---|---|---|
| RS-15 / RS-25 | 9.9W ~ 27.36W | 3.3V, 5V, 12V, 15V, 24V, 48V | Up to 86% |
| RS-35 / RS-50 | 23.1W ~ 52.8W | 3.3V, 5V, 12V, 15V, 24V, 48V | Up to 89% |
| RS-75 / RS-100 | 49.5W ~ 110.4W | 3.3V, 5V, 12V, 15V, 24V, 48V | Up to 89.5% |
| RS-150 | 99W ~ 158.4W | 3.3V, 5V, 12V, 15V, 24V, 48V | Up to 86% |
RD & RID Series: Dual Output (35W ~ 125W)
The dual output series is split into standard configurations (RD) and isolated output configurations (RID) for systems requiring independent grounds to eliminate noise loops.
Key Differences
- RD Series: Standard dual output sharing a common ground.
- RID Series: Features Isolated output & GND for CH1 and CH2. Specific RID-125 models (1205/2405) support a 170% peak load for CH1.
Dual Output Configurations
| Configuration Code | Output CH1 | Output CH2 | Applicable Series |
|---|---|---|---|
| A | 5V | 12V | RD / RID (All Wattages) |
| B | 5V | 24V | RD / RID (All Wattages) |
| 13 | 13.5V | -13.5V | RD-35 only |
| 1224 / 1248 / 2448 | 12V / 12V / 24V | 24V / 48V / 48V | RD-125 / RID-125 |
| 2412 / 4812 / 4824 | 24V / 48V / 48V | 12V / 12V / 24V | RD-125 (Standard only) |
| 1205 / 2405 | 12V / 24V | 5V / 5V | RID-125 (Isolated only) |
RT & RQ Series: Triple & Quad Output (50W ~ 125W)
Designed for complex systems requiring multiple voltage rails, such as motherboards, logic controllers, and mixed-signal environments.
RT Series (Triple Output)
| Code | CH1 | CH2 | CH3 |
|---|---|---|---|
| A | 5V | 12V | -5V |
| B | 5V | 12V | -12V |
| C | 5V | 15V | -15V |
| D | 5V | 24V | 12V |
RQ Series (Quad Output)
| Code | CH1 | CH2 | CH3 | CH4 |
|---|---|---|---|---|
| B | 5V | 12V | -5V | -12V |
| C | 5V | 15V | -5V | -15V |
| D | 5V | 12V | 24V | -12V |
