СКР-7001

DC-DC module 2000 W, 400 V input

Converts high voltage from the surface to the vehicle working voltage. Allows power transmission over a thin tether across hundreds of metres without losses.

Specifications

28 V or 48 V output
Over- and under-voltage protection with automatic recovery
Overload and short-circuit protection
Overheating protection
Output voltage adjustable from minus 20 to plus 10 percent
Base temperature range from minus 40 to plus 100 °C

СКР-7002

DC-DC module 2000 W, 800 V input

Same for a higher input voltage: for long tethers and high-power vehicles.

Specifications

28 V or 48 V output
Full protection set with automatic recovery
Adjustable output voltage
Base temperature range from minus 40 to plus 100 °C

СКР-7003

AC-DC power supply 3000 W

Surface or shipboard power supply: converts mains to high voltage for transmission down the tether.

Specifications

220 V AC input
200-300 V DC output
High power factor, low harmonics
Several modules can be operated in parallel

СКР-7004

AC-DC power supply 30 kW

High-power supply for work-class vehicles. Requires a three-phase connection.

Specifications

Three-phase 380 or 480 V AC input
200-1000 V DC output
Digital control
Built-in reverse-current protection, self-isolating on failure

СКР-7005

Ethernet over powerline module

Carries video and commands over the same cable as power. The tether becomes thinner, lighter and cheaper.

Specifications

IEEE 1901 and HomePlug AV standards
Up to 500 Mbit/s
Small footprint, low heat output

Позволяет передавать данные по тому же кабелю, что и питание

СКР-7006

Powerline and switch board

Same plus a built-in network switch: four devices on one tether - cameras, sonar, sensors.

Specifications

IEEE 1901 and HomePlug AV standards
Up to 500 Mbit/s
Built-in four-port 100 Mbit/s switch
Small footprint

СКР-7007

Rotary subsea switch

A switch that operates subsea: change modes without recovering the vehicle.

Specifications

2, 4 and 8 position versions
Position feedback
Rated for 2000 cycles
1000 m depth rating

СКР-7008

7-segment LED display

Single-digit display for mounting in an end cap. Shows mode number, error code or voltage - no computer needed to read the state.

Specifications

0.28 inch digit height
Common anode
Mounts into the end cap

СКР-7009

M8 subsea switch

A switch that works subsea: changes mode without recovering the vehicle. Mounts directly into the hull wall.

Specifications

M8 thread
Operates underwater
Mounts into the housing wall

СКР-7010

Non-magnetic push button switch

A button with no moving parts through the hull: it actuates through the wall. No opening means no path for water.

Specifications

Actuates through the housing wall
No through-hole in the housing
Board-level version for integration

СКР-7011

Rotary waveband subsea switch

Multi-position rotary switch: selects mode, channel or speed. Operates subsea.

Specifications

Several detented positions
Operates underwater

СКР-7012

Rotary on-off subsea switch

Simple on-off by rotation. Used as the vehicle master switch.

Specifications

Two positions
Operates underwater
Used as the main power switch

СКР-7013

Underwater rotary potentiometer

Continuous adjustment subsea: light output, sensitivity, setpoint. Unlike a switch, it gives a smooth value rather than steps.

Specifications

Continuous adjustment
Operates underwater

СКР-7014

Push button relay

Push button latched through a relay: one press turns on, the next turns off. No need to hold.

Specifications

State latched through a relay
Single-button control

СКР-7015

MOS low-side switch

Electronic switch for controller-driven loads: turns a light or thruster on by signal, with no mechanical contacts.

Specifications

Driven by a controller signal
No mechanical contacts
For lights and thrusters

СКР-7016

Pressure switch

Trips at a preset pressure. Used as a leak alarm: rising internal pressure means water ingress.

Specifications

Triggers at a pressure threshold
Used for leak monitoring

СКР-7017

Tap switch

Momentary button for issuing a command: reset, calibration, mode start.

Specifications

Momentary action
Watertight construction
