Quick Answer
HYSF power connectors support 5A to 100A depending on size and configuration. Standard 2-pin: 10-20A. Large multi-pin: 30-50A per contact. High-power dedicated: up to 100A. Voltage ratings: 300V to 1000V. Contact us for custom high-power solutions.
Current Ratings by Connector Series
| Series | Pin Count | Current per Pin | Max Voltage | Application |
|---|---|---|---|---|
| Micro | 2-4 | 5A | 300V | Sensors, small devices |
| Standard | 2-12 | 10-20A | 500V | ROV tools, cameras |
| Power | 2-6 | 30-50A | 750V | Thrusters, manipulators |
| High-Power | 1-4 | 50-100A | 1000V | Main power, charging |
Power Connector Selection
Low Power (5-10A)
- Applications: Sensors, LED lights, small cameras
- Connector size: Micro or mini series
- Wire gauge: 20-16 AWG
- Typical use: Signal + low power combined
Medium Power (10-30A)
- Applications: HD cameras, small thrusters, tools
- Connector size: Standard series
- Wire gauge: 16-12 AWG
- Typical use: ROV payload power
High Power (30-100A)
- Applications: Main thrusters, manipulators, charging
- Connector size: Power or High-Power series
- Wire gauge: 12-4 AWG
- Typical use: Vehicle main power
Voltage Ratings
| Rating | Application | Safety Margin |
|---|---|---|
| 300V | Low voltage DC systems | 2x operating voltage |
| 500V | Standard ROV/AUV systems | 2x operating voltage |
| 750V | High power industrial | 1.5x operating voltage |
| 1000V | Special applications | 1.5x operating voltage |
Power + Signal Hybrid Connectors
Many HYSF connectors combine power and signal in one unit:
- Example: 2 power pins (20A each) + 4 signal pins (5A each)
- Benefit: Single connection point, reduced weight
- Consideration: Proper pin assignment and isolation
Thermal Considerations
Heat Dissipation
- Higher current = more heat generation
- Underwater environment helps cooling
- Derate by 10-20% for continuous high-load use
Voltage Drop
- Consider cable length in voltage drop calculations
- Longer cables = larger gauge needed
- Typical acceptable drop: <3% of supply voltage
Safety Features
- ✅ Keyed connectors prevent mis-mating
- ✅ Polarized pins prevent reverse connection
- ✅ Insulated contacts prevent short circuits
- ✅ Pressure-resistant housing prevents water ingress
Custom High-Power Solutions
For applications requiring >100A:
- Custom contact designs available
- Multiple parallel connectors option
- Active cooling considerations
- Engineering consultation required
How to Specify Power Requirements
When ordering, provide:
- Maximum current (amps)
- Operating voltage (volts)
- AC or DC
- Number of power circuits needed
- Any signal lines needed
- Cable length and gauge
