An introduction to the product

1.1 Product description

SDN-P series waterproof controller products include SDN-P10A, SDN-P20A
two specifications, w hich ar e intende d mainly for use in sma ll solar inde pende nt pow er
generation system s.

With this equipment, it is possible for the solar cell panel to perform the charge
management on the battery as well as for the battery to carry out load discharge on the
battery. This equipment has perfect protection functions. There are various control
modes and manual switching on/off is available. It can be widely used in solar power
small power station system. In addition, it also can be used in the solar energy street
lamp system together with the LED constant current source.

1.2 Main features

 For the full range -35~55°C, it can perfor m long-term full load operation, with an
high efficiency and a low power consumption
 It is compatible with the lead-acid type battery, the colloid type battery, the lithium
type battery and ot her ty pes of bat ter y

 It has six period l oad control a nd the length of e a ch pe r iod is adju stable separately.
 It is of a compact design, with a small size and high perf or m anc e - price ratio; it can

be installed in a narrow space and is of a f ully waterpr oof design IP 67
 It has comprehens ive pr ot ect i on fu nct i o ns; the controller itself and the external
equipment will not be damaged in case of various abnormal conditions such as short
circuit, open circuit, super power and so on

 The pure aluminum shell design facilitates the heat dissipation
 It has the ex pandable Intelligent Human Induction Function
