DC Power Distribution Terminal Blocks with Per-Channel Independent Switches
Modular DC distribution up to 72 V / 20 A per channel, available in screw or spring types.
Per-channel independent switches let you isolate circuits safely without shutting down the system.
The AOSI DC power distribution terminal block series provides reliable low-voltage wiring solutions for control panels and power systems. Each module integrates one DC input and multiple output channels, supporting up to 72V 20A per circuit.
Users can select standard models or independent switch DC modules, which allow each channel to be turned on or off individually for safer maintenance.
Available in 2 to 16 channels, the FM06 Series delivers stable, high-current distribution up to 72 V / 20 A per channel. These DC power distribution terminal blocks feature durable screw connections that ensure secure wiring even in vibration-prone environments.
主な特徴
2–16 channel options with modular housing
Screw connection for strong and stable contact
Rated for 72 V DC / 20 A per channel
Compatible with 35 mm DIN rail installation
The HM06 Series is designed for flexibility and easy maintenance, offering per-channel independent switches that allow each circuit to be isolated individually.
主な特徴

Rated for 72 V DC / 20 A per channel
Compact, space-saving DIN-rail design
The AOSI independent switch terminal block enables true per-channel control—you can isolate, test, or service a single branch without powering down the entire system. This design effectively acts as a compact dc circuit isolation module, improving safety, shortening maintenance time, and keeping adjacent loads running.
Quick Benefits at a Glance
✅ 1Individual ON/OFF per branch for safer live maintenance
✅ RFaster troubleshooting; isolate only the faulted load
✅ ENo system-wide downtime; adjacent channels stay powered
✅ SClear visual state (switch position and optional LED)
| Feature / Outcome | With Independent Switch | Without Independent Switch |
|---|---|---|
| Per-channel isolation | Yes (instant) | No (requires upstream disconnect) |
| Live maintenance safety | 高い | Medium |
| Troubleshooting speed | Fast (single branch) | Slower (affects more loads) |
| System uptime during service | Maintained | Often interrupted |
| 最適 | Test/repair-intensive panels, PV strings, battery branches | Simple, rarely serviced circuits |
Typical Use Cases
AOSI offers two connection styles for its DC power distribution terminal blocks, giving engineers the flexibility to match installation preferences and cabinet requirements.
Both types support up to 72V / 20A per channel and are available from 2 to 16 channels.
Choose between the FM06 screw terminal DC blocks for high vibration environments or the HM06 spring clamp DC distribution modules for fast, tool-free wiring.
