Emerson charging modules HD22005-3A and HD11010-3A are important configuration modules in power supply systems and are widely used in substation DC power supplies. The following are the main features and functions of these two charging modules:

HD22005-3A module Features:

Output parameters: Nominal output voltage is DC220V, nominal output current is 5A, and output power reaches 1300W.

Protection function:

Input over/Under voltage protection: When the input voltage is less than the under voltage set value or greater than the over voltage set value, the module will enter the protection state, no DC output.

Output overvoltage protection/Undervoltage alarm: When the output voltage exceeds the normal range, the module provides corresponding protection and alarm.

Short-circuit retraction: When the module output is short-circuited, the output current is limited to 40% of the rated current.

Phase loss protection: When the input is out of phase, the module limits the power output, but can still be half-loaded output.

Overtemperature protection: When the internal temperature of the module is too high, the module will stop working to prevent damage.

Communication function: The module supports RS485 mode to communicate with the host computer, which can send and receive voltage, current, protection and alarm information in real time.

Modulation mode and connection mode: pulse width modulation (PWM) mode and full bridge transistor connection mode.

Other functions include fan temperature control and fault display.

HD11010-3A module (Since there is less specific information about the HD11010-3A module directly, but considering its similarity to the HD22005-3A series, the following are some speculative descriptions) :

Functional similarity: Although there is less detailed information about the HD11010-3A directly, it can be inferred that its functions are similar to the HD22005-3A, including protection functions, communication functions, etc.

Size and appearance: The HD11010-3A may be similar or similar in size and appearance to the HD22005-3A.

Installation and maintenance: Since both belong to the same series, installation and maintenance methods may also be similar.

In SUMMARY:

The Emerson Charging modules HD22005-3A and HD11010-3A are important charging modules in power supply systems with a variety of protection and communication functions to ensure the stable operation of power supply systems. These two modules have been widely used in DC power supply of small substations.
