The 200A DC contactor is designed special work with CHARGERY BMS, the following are some features:

• Bi-directional connection, one DCC can be used in a Common port such as a Solar system, instead of two SSR's (Solid State Relays) or conventional relays.
• The DCC has a Built-in the surge suppressing circuit, thereby eliminating the need for the additional Relay Delay Time board which is used to avoid a surge current when starting to charge or discharge. For other SSR's or mechanical relay, please consider the surge current potentials seriously and make a suitable plan for using a delay board as applicable.
• Over temperature protection. If internal temperatures over heat, the contactor will shut off.
• One Intelligent cooling fans turned on automatically
• Approved by CE
• 12 months warranty

Specification

Two models must be confirmed before purchasing

DCC-300HB-C, used on charge and discharge on common port

DCC-300HB-S, used on charge and discharge on separate port

Installation

Install DCC on battery positive, the ISO board muse be connected to DCC and BMS, as below,

CHARGERY design and manufacture all products with Chargery brand,

We have two core technologies, we can design high frequency switch charger/power supply, It means high voltage, high power converter with high efficiency (up to 94%), at the same time we can design BMS with high accuracy on voltage and current measurement and built-in large current cell balancer.

When we integrated the two core technology, our charger and BMS can communicate each other, the result is don’t need cut off charging by DCC or Relay, not only shorten charging time, but also extend battery life. Save money and decrease system complexity.

We are happy to modify and/or optimize design, or add new features to meet any requirements from our customers.

CHARGERY is almost unique company in the UAV (RC model, big drones) and EV (e-bike, e-motocycle, e-scooter) market, we can develop high power AC charger and BMS by one develop team.

From 2006, we focus on developing high power (up to 60A 3000W) charger, balance charger (AC input, DC input and AC/DC dual input) and BMS for up to 24S LiPo/LiFe/ LiTO battery.

Chargery charger can charge any type battery including LiPo, LiFe, Li-ion, LiTo, NiMh, NiCD and Pb (Lead acid, VRLA battery), cell count, charge current, end voltage and end current can be programmed.

Chargery BMS can handle up to 800A charge and discharge current, fit with special DCC (DC contactor), anti-spark and reverse polarity protection when battery connect to charge or inverter(loader) is realized.
