Interface Module CT-211
Plug-in interface module for use as a battery charger
What is the CT-211 Easy Charger Wizard?
The CT-211 Easy Charger Wizard is a plug-in interface module from Cotek that allows standard power supplies from the AE and AEK series (Low Voltage) to be programmed as 3-stage battery chargers. This makes it possible to charge various battery types, sizes, and voltages (12V, 24V, 48V) using a single power supply.
What functions does the CT-211 offer?
- 3-stage charging function: Supports the Bulk, Absorption, and Float charging phases.
- Flexibility: Compatible with various battery technologies (e.g. Lead-Acid, Gel, AGM, Lithium).
- Connection: Connects via the power supply's auxiliary port.
- Programming: Can be configured via RS232 or RS485.
- Voltage range: Supports 12V, 24V, and 48V battery systems.
How do I program the CT-211 Easy Charger Wizard?
- Install software: Install the Easy Charger Wizard software on a PC.
- Establish connection: Connect the CT-211 to the PC via RS232/RS485.
- Set parameters:
- Bulk charge: Set the voltage and current for the main charging phase.
- Absorption: Set the voltage and time for the absorption phase.
- Float charge: Define the voltage for the float charge.
- Save: Transfer the settings to the CT-211 module.
Do I need additional hardware to use the CT-211?
- CT-211 module: Included in the scope of delivery.
- Connection cable: Supplied.
- RS232/RS485 adapter: If not available, an adapter may be required for communication with the PC.
External Power Supplies (Plug-in and Desktop Power Supplies)
Find practical answers to frequently asked questions about our external plug-in and desktop power supplies for industrial, medical, and IT applications. These articles support you with selecting the appropriate model, navigating country-specific mains plug options, and ensuring safe commissioning and troubleshooting.
Worauf muss ich bei der Auswahl eines passenden externen Netzteils achten?
For an external power supply unit (e.g. a desktop power supply) to operate safely, four criteria must match your device: voltage, current, polarity, and connector dimensions. You will usually find the required ratings on your device’s rating plate (typically under "Input") or on your previous power supply under "Output".
- Voltage (volts / V) – must match exactly: The output voltage of the power supply unit must match your device's input voltage precisely. Excessive voltage can permanently damage the electronics; insufficient voltage will cause the device not to start or to run unstably.
- Current (amperes / A) – may be higher: The power supply unit must supply at least the current required by the device. A higher ampere or wattage rating on the power supply poses no risk, as the device only draws the current it actually requires.
- Polarity – must match: Check the polarity symbol on the device. DC barrel connectors are usually centre-positive (positive pole inside). The replacement power supply must have identical polarity.
- Connector dimensions (DC barrel connector): The connector must fit securely and smoothly into the socket. Common dimensions specify the outer and inner diameters (e.g. 5.5 × 2.1 mm or 5.5 × 2.5 mm). If socket dimensions are non-standard or unclear, universal power supplies with an adapter set can help.
