Key Features
30V 30A 900W Adjustable DC Power Supply for High Current Battery Systems
The R-SPS3030C provides adjustable 0–30V voltage and up to 30A current, with a maximum output power of 900W.
For High Current Battery Systems, battery capacity and charging requirements can vary depending on the compatible battery system and application. The adjustable voltage and current output allows users to configure charging and power parameters within the rated range of the power supply.
With up to 30A output current and 900W maximum power, the R-SPS3030C provides high-current output capability for compatible rechargeable battery applications.
Battery Charging Function for Controlled Battery Charging
The R-SPS3030C includes a dedicated Battery Charging Function for compatible rechargeable battery charging applications.
Users can configure the required voltage and current parameters according to the requirements of the compatible battery system before charging. The adjustable output provides flexibility when working with different charging conditions within the rated 0–30V and 0–30A output range.
The charging function makes the R-SPS3030C suitable for users who require an Adjustable DC Power Supply for battery-related applications in addition to general DC power output.
Reverse Polarity Protection for Battery Connection
The Battery Charging Function includes Reverse Polarity Protection to help prevent damage caused by incorrect battery connection.
When connecting compatible batteries, correct polarity is important during charging operations. The reverse polarity protection function provides additional protection when an incorrect battery connection occurs.
When the battery is connected correctly, the charging status indicator provides a visual indication of the charging condition.
Overcharge Protection with Automatic Output Shutoff
The R-SPS3030C includes Overcharge Protection during battery charging operations.
When a compatible battery reaches a fully charged condition, the power supply can automatically switch off the output to help prevent continued charging. After the output is automatically switched off, the BATTERY indicator changes to green.
This automatic output shutoff function provides practical charging protection for compatible High Current Battery Systems.
OCP Protection for High-Current Battery Applications
The built-in OCP (Over Current Protection) provides an additional protection function when excessive current conditions occur.
For high-current battery applications, unexpected output current conditions may occur depending on the connected equipment or operating conditions. OCP helps provide protection for the power supply and connected load during operation.
Combined with the adjustable current setting, this function provides practical support for controlled operation within the rated output range.
M1–M3 Memory for Frequently Used Battery Parameters
The R-SPS3030C provides M1–M3, 3 groups of memory function, allowing users to save frequently used voltage and current settings.
For users working repeatedly with the same compatible battery systems, commonly used charging parameters can be stored and recalled without manually entering the same settings each time.
This function is useful for repeated charging and testing operations involving predefined voltage and current conditions.
Precision Adjustment and 4-Digit Display for Battery Monitoring
The precision encoder allows users to make controlled adjustments to voltage and current settings.
The 4-digit display provides clear monitoring of voltage, current, and power information during operation. During battery charging, users can also monitor real-time charged power information.
Together, the precision adjustment and real-time display functions help users configure and monitor output conditions when working with compatible High Current Battery Systems.
Front and Rear Dual Output Ports
The R-SPS3030C features both front-panel and rear-panel output ports for flexible connection.
The front-panel output supports loads below 5A, making it suitable for convenient lower-current charging and testing tasks. The rear output can be used at full rated power, providing access to the complete 900W output capability.
For applications requiring higher current, the rear output provides a suitable connection option within the rated specifications of the power supply.
Panel Lock and Adjustable Buzzer
The Panel Lock Button helps prevent unintended changes to voltage and current parameters after the required charging settings have been configured.
This can be useful during extended battery charging operations where maintaining the selected settings is important.
The control knob also includes a buzzer, which can be set to mute according to user preference during operation.
