Long press the SET button for 5 seconds to save and exit. Parameters Defined UP (Upper Limit): High voltage threshold. dn (Lower Limit): Low voltage threshold.
Crucial Note: This device is ; it does not change, step up, or step down voltage. It simply operates its internal relay like an on/off switch based on the battery parameters you program.
: Connect the battery or power source to the VIN+ and VIN- terminals.
A: The battery symbol appears when voltage drops below 1.35V. Replace the LR44 immediately. Ignoring it leads to random numbers. xycd60 manual
This flashlight offers two distinct control interfaces. You can use the tail switch as the primary master power control for turning the light on or off, and the side switch to cycle through modes and settings.
Given the ambiguity of the model number, here is a final guide to help you find the correct information:
Set (Upper Limit): The voltage at which the load turns ON. Long press the SET button for 5 seconds to save and exit
| Battery Type / Voltage | Upper Limit (UP, overcharge) | Lower Limit (dn, cut‑off) | | :--------------------- | :--------------------------- | :------------------------- | | 12V Lead‑Acid (AGM/GEL) | 14.4 V – 14.7 V | 10.5 V – 11.0 V | | 12V LiFePO₄ | 14.4 V – 14.6 V | 10.0 V – 11.0 V | | 24V Lead‑Acid | 28.8 V – 29.4 V | 21.0 V – 22.0 V | | 48V Lead‑Acid | 57.6 V – 58.8 V | 42.0 V – 44.0 V |

is and cannot alter voltage or limit current . Instead, it uses an onboard relay to mechanically connect or disconnect your power source or load based on your customized upper and lower voltage parameters. Technical Specifications Specification Operating Voltage DC 6V to 60V Control Precision Output Type Relay Output (Physical Switch) Supported Batteries Lead-Acid, Lithium-Ion, LiFePO4, etc. Power Consumption < 1.5W (Approx. 30mA operating current) Physical Dimensions ~79mm x 43mm x 27mm Core Operating Modes Crucial Note: This device is ; it does
When the detected battery voltage falls below or equals the configured Lower Limit Voltage ( dn ), the onboard relay turns ON (closes the circuit), and external charging current flows into the battery. The display flashes "IN".
| Parameter | Meaning | Example Setting (12V Lead‑Acid) | | :-------- | :------------------------------ | :------------------------------- | | | Upper voltage limit (overcharge protection) | 14.4 V (charging stop) | | dn | Lower voltage limit (over‑discharge protection) | 10.5 V (load disconnect) | | OP | Maximum on‑time (minutes:seconds). Set 00:00 to disable. | 01:30 | | dOP | Delay‑on time (seconds) before restarting after a cycle completes | 030 (30 seconds) | | FOP | Discharge mode only . Forces relay ON for 0–10 seconds to stabilise load | 003 (3 seconds) |
Set (Down Limit): The voltage at which the charger starts (Battery Low). When battery voltage >UPis greater than cap U cap P , the output turns off. 4. Parameter Setting (How to Program)
