Utilizing toroidal transformer

ARD-3 utilizes a toroidal transformer as a key component for inverting and boosting, with high conversion efficiency, saving battery energy. Additionally, the flexible design of the toroidal transformer's diameter and height makes the overall product structure more reasonable and safer.

Capable of providing AC380V and AC220V power simultaneously

ARD-3 can simultaneously provide AC380V and AC220V power, suitable for situations where door machine or brake power is directly taken from phase voltage rather than the output of the control transformer.

Strong overload capacity

ARD-3 adopts imported low-voltage high-current MOSFETs in parallel to form a full-bridge inverter switching circuit, with strong overload capacity. It can withstand current surges caused by the powering of the elevator control cabinet, contactor engagement, brake opening, and traction machine startup.

Strong voltage regulation performance

Strong voltage regulation performance. ARD-3 employs an innovative internal digital constant voltage control method to ensure that during the rapid consumption of battery energy during operation, it can fully utilize the remaining battery energy to stabilize the output voltage, ensuring the smooth completion of the rescue process.

Uses environmentally friendly, pollution-free lithium batteries

This product uses lithium batteries, which have the characteristics of high voltage, light weight, and long lifespan. Lithium batteries also have low self-discharge and no memory effect. Adding a protection board to lithium batteries can achieve overcharge and over-discharge protection. Importantly, lithium batteries are green, environmentally friendly, and pollution-free.
