Product Description

Features of  SR-EH120

1.With an all-new wireless remote control design, a hand-held device can be used to modify controller parameters and read system information.
2.Fully-digital and high-precision constant current control boasting an efficiency of up to 96%.
3.Supports 12 V and 24 V lead-acid batteries and lithium batteries.
4.Features a DC detection function. If DC available, the system will automatically switch to DC power supply when the battery voltage falls to the DC switching point; if DC powers off, the system will shut off output when the battery reaches the over-discharge point after continuous discharging.
5.Boasts an adjustable operating current range of 0.15 A from 3.96 A and an adjustment precision of 30 mA.
6.Employs a load triple-stage dimming and morning light design, with an operating duration adjustable from 0 to 15 hours and a power settable from 0 to 100%.
7.Data communication adopts a multi-time two-way handshake protocol and a data compression algorithm, realizing precise and fast data transmission.
8.True constant current rather than current-limiting control ensures smooth and stable output current, effectively reducing LED light attenuation and extending LED service life.
9.A metal case and an IP68 waterproof level enable the device to operate in various kinds of tough conditions.
10Adopts an improved charging algorithm to reduce the vulcanization effect caused by battery over-discharging, significantly extending the battery's service life.
11.An overheat protection function enables the device to scale down the load or shut off the load completely when its temperature exceeds a certain point.
12.A range of protection measures such as battery reverse-connection protection, LED short-circuit and open-circuit protection, etc., put the system under comprehensive and constant guard.
