Ultra-Wide Voltage Version (DC 3V–30V Input) with Over-Voltage Protection
Product Overview The DSLRKIT USB Type-C to CR2032 Dummy Battery Adapter provides a continuous external power source for devices originally powered by CR2032 coin cells. Version 3.0 features an upgraded circuit design, expanding the input voltage tolerance up to 30V and integrating hardware-level over-voltage protection.
Key Features
-
Ultra-Wide Input & Over-Voltage Protection (V3.0 Upgrade): Supports a DC 3V–30V input range. The V3.0 PCB integrates a TVS (Transient Voltage Suppressor) diode to protect against voltage surges.
-
Precision Engineering: Manufactured using an actual-dimension CR2032 metal housing for reliable electrical contact.
-
Detachable Installation (V3.0 Upgrade): Features an exposed FPC connector, allowing the 8.5cm FFC cable to be detached and threaded through narrow gaps before reattachment.
-
Stable 3V Output: Delivers a stable DC 3V nominal output, equivalent to a fresh CR2032 cell.
Technical Specifications
-
Input Interface: USB Type-C (Universally compatible with standard and PD/QC power sources)
-
Output Voltage: DC 3V
-
Input Voltage Range & Load Capacity (Continuous / Peak Pulse):
-
DC 3~5V: 100mA / 0.3W (Peak: 200mA / 0.6W)
-
DC 12V: 20mA / 0.06W (Peak: 80mA / 0.24W)
-
DC 24~30V: 5mA / 0.015W (Peak: 20mA / 0.06W)
-
Note: This power capacity is sufficient to meet the power requirements of all devices using CR coin cells.
Important Usage Notice
-
Strictly Single Cell Use Only: DO NOT use this adapter in any series or parallel configuration. Connecting multiple dummy cells together will cause permanent damage.
-
Rule: Only one dummy cell and one adapter should be used per device at a time.
Application Scenarios
-
Recommended For: Devices fixed at a known location, long-duration sensors and LCD displays, equipment requiring uninterrupted operation.
-
Not Recommended For: Frequently moved equipment, portable handheld products.
