What’s the Maximum Current Rating for HYSF Power Connectors?

빠른 답변

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

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

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)
• 혜택: 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
