Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://brlabelectronics.gitbook.io/hardware-1/technical-specifications/absolute-maximum-ratings.md). # Absolute Maximum Ratings These are technical specifications for the relay shield. Please refer to the development board datasheet for specific technical details about the board you are using.

Parameter	Typ	Max	Unit
Supply Input Voltage		+14	V
Battery Input Voltage		+6.5	V
Buck Converter Supply Voltage		+5.5	V
Buck Converter Supply Current		3	A
Boost Converter Supply Voltage		+5.5	V
Boost Converter Supply Current		2	A
3V3 Power Supply	+3.3		V
3V3 Supply Current	1.35		A
Power Relay Switching Voltage		250, 30	VAC, VDC
Power Relay Switching Current (Resistive Load)		10	A
Power Relay Switching Current (Inductive Load)		5	A

Using the board beyond the absolute maximum ratings listed above may cause permanent damage to the board and possibly the development board. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://brlabelectronics.gitbook.io/hardware-1/technical-specifications/absolute-maximum-ratings.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
