Technical Highlights

Two Verified Output Variants

The series includes the Ultra1600 with selectable output up to 1600mW and the Ultra2500 with selectable output up to 2500mW. Both models also support Pit mode and lower output settings for setup, testing and different FPV operating requirements.

64-Channel Analog Video Transmission

The VTX provides 64 channels across eight frequency bands. The supplied frequency table covers 4990–5945MHz, allowing the operator to select a compatible channel for the receiving system and permitted operating region.

IRC Tramp Control

IRC Tramp support enables compatible flight-control systems to adjust VTX parameters through the on-screen display. A physical function button and separate power, band and channel indicators are also provided for direct configuration.

Wide 2–8S Power Input

The transmitter accepts DC 7–36V input for use with 2–8S battery systems. A regulated 5V/600mA output is available for powering a compatible FPV camera or cooling fan.

Thermal Management Structure

A two-layer board structure separates the power BEC section from the main board. The design incorporates a heatsink and temperature-control protection, while adequate airflow remains necessary during operation.

Integrated FPV Audio and Video Support

The VTX supports PAL and NTSC analog video, uses a 75Ω video input and includes a built-in microphone for compatible FPV receiving equipment.

Model Selection Guidance

Select the Ultra1600 when a maximum output of 1600mW and a 200mW intermediate setting are required.
Select the Ultra2500 when output settings of 1500mW and up to 2500mW are required.
Actual usable range depends on the selected frequency, antenna system, receiver sensitivity, installation, terrain and local RF conditions.
Verify that the selected frequency and output power are permitted in the intended operating region.

Installation Notes

Install a suitable antenna before powering the VTX. Operating without an antenna can damage the RF output stage.
Use an antenna designed for the selected operating band.
Provide continuous airflow around the heatsink, especially when using higher output settings.
Add a cooling fan when the VTX is installed inside an enclosed or poorly ventilated frame.
Use the regulated 5V output only for a compatible FPV camera or cooling fan.
Do not connect battery voltage or another power input to the 5V output terminal.
Confirm wiring polarity before applying power.

FAQ

What is the difference between the Ultra1600 and Ultra2500?

The Ultra1600 provides selectable output up to 1600mW, including a 200mW setting. The Ultra2500 provides selectable output up to 2500mW and includes 1500mW and 2500mW settings.

How many channels does this VTX support?

Both models support 64 channels across eight frequency bands. The supplied channel table covers 4990–5945MHz.

Can the VTX be configured through the flight controller?

Yes. The VTX supports IRC Tramp control for parameter adjustment through a compatible flight controller and OSD system.

What battery voltage can be connected?

The input accepts DC 7–36V and is compatible with 2–8S battery systems. Always verify wiring polarity before connecting power.

What is the 5V output used for?

The regulated 5V/600mA output is intended for a compatible FPV camera or cooling fan. It must not be connected to battery voltage or used as the main VTX power input.

Does the VTX require additional cooling?

Adequate airflow is required, particularly at higher output settings. A cooling fan should be considered when the VTX is installed in an enclosed or poorly ventilated location.

Can the transmitter be powered without an antenna?

No. A suitable antenna must be connected before power is applied. Operating the VTX without an antenna can damage the RF output stage.

B2B Procurement FAQ

Which model information should be included in an inquiry?

Please specify Ultra1600 or Ultra2500, required quantity, destination market and any technical documentation needed for integration review.

Can Ultra1600 and Ultra2500 be managed as variants of one product?

Yes. They share the same dimensions, mounting pattern, channel configuration, connectors and control protocol, so they can be presented as selectable variants. Their output-power settings and model labels must remain clearly separated.

Can both output variants be included in one purchase order?

Mixed-variant ordering may be requested, but availability, quantity allocation and order handling must be confirmed during quotation.

What should be confirmed before placing a bulk order?

Confirm the selected model, required quantities, permitted operating frequencies, output-power requirements, stock status, lead time, packaging and any applicable compliance documentation before order approval.

What mechanical information is available for integration?

Both models measure 36.5 × 36.5 × 12mm, weigh 15g without the cable and use a 30.5 × 30.5mm M3 mounting pattern. Installation must also provide sufficient antenna clearance and cooling airflow.
