Mainstation MST1 by cmotion
Overview
The Mainstation MST1 comes in to address all of those problems by being three devices in one: 1. Power Source Manager, 2. Multi-Rail Power Converter, 3. Universal Smart Charger.
1. Power Source Manager
Three Universal Battery Mounts
- New location, new battery mount?
- No problem. Swap the battery plates. All industry standard mounts, all voltages. Current options are Bebob B-Mount, IDX V-Mount and Gold Mount. Additional industrial options to follow.
- Need more power?
- Up to three battery inputs working in parallel provide unprecedented output capabilities. 10 – 34VDC – up to 20A per channel.
- Always-on?
- Remote heads, underwater rigs or other scenarios where loss of power will be critical are no longer a concern. All inputs are hot-swappable.
- Safety and damage concerns?
- All inputs are independent and digitally controlled. This is not a serializer. Batteries will not cross-charge.
- Voltage and setup concerns?
- No setup startup and built-in over and under-voltage protection, as well as overcurrent monitoring, will ensure safe and reliable operation in any scenario.
2. Multi-Rail Power Converter
Six Regulated Outputs
- Always-on
- If at least one of the five inputs is valid, the Mainstation MST1 provides six independently regulated outputs.
- Two high power XLR outputs
- Run cameras, arrays, remote heads, monitors and anything else.
- Four accessory outputs
- Run video transmitters, small monitors, LBUS devices and charge laptops with full 100W PD3.0 power.
- All, at the same time.
- High Power XLR Outputs
- Power any – or multiple devices – from any input available.
- XLR4 Output
- User selectable range: 14.8 to 16.8V · 300W peak output – in 28V Mode
- XLR3 Output
- User selectable range: 28.8V to 33V · Massive 700W peak output* · Power multiple camera array rigs, powerful remote heads and handle extreme movement transients.
3. Universal Smart Charger
Three bay charging
- Charging profile
- Automatically set – 16.8V or 33.5V.
- Charging current
- Variable based on system load and input source. Full specs TBA.
- Battery float voltage
- Automatically set.
- Battery communication
- Yes (if available)
- Independent charging profiles
- Yes
- Charging source
- XLR3 Input
- Charging setting
- Automatic or user-enabled.
Closing the power circle, the Mainstation MST1 includes a built-in smart charging module for each battery bay.
Universal Battery Plate
The UBP1 is designed as an interface between all mechanical battery mounts currently on the market and the Mainstation MST1.
Power — Designed for 10-34VDC – 20A input.
Battery communication — There are three pins available for battery communication. Expected protocols are SMBus and 1-Wire.
Heavy duty bottom screw mounts — 2 x 3/8 – 20 UNC industry standard threads
