Products Description
The 48990001-NK DSSR122 Power Supply Unit can convert the DC input power (DC-input) into a stable DC output (DC-output), typically at 24 V DC, to supply power to PLCs, DCSs, I/O modules, and field auxiliary equipment. The module is designed for DIN rail or rack installation, supports long-term stable operation in industrial environments, and features overvoltage, overcurrent, and short-circuit protection functions.

Products Description
1. Adapt to different DC power sources
The DSSR122 48990001-NK Power Supply Unit can accept common DC inputs in industrial environments, such as 24 V DC, 48 V D, or 60 V DC (depending on the specific system configuration). This means that even if different devices or cabinets use different voltage levels of DC power, the DSSR122 can operate stably without the need to change the input lines or add additional adapters.
2. Tolerating voltage fluctuations
In industrial environments, the DC power supply may experience certain amplitude fluctuations (approximately ±10%). The DSSR122 Power Supply Unit incorporates a voltage stabilizing function, which can convert the fluctuating input voltage into a stable output, ensuring that the PLC, I/O modules, and auxiliary equipment will not malfunction or shut down due to input fluctuations.
3.Uniform output voltage
Regardless of changes in the source of the input DC power, DSSR122 48990001-NK Power Supply Unit can output a standard 24 V DC. This characteristic of "multiple input sources but uniform output" makes the wiring in the control cabinet more concise and ensures that various devices can operate safely and reliably under the same voltage.
4.Support for system upgrade and expansion
When expanding or modifying the system, it may be necessary to connect new power sources or integrate devices with different voltages. DSSR122 48990001-NK is compatible with these various DC inputs, making system upgrades or module expansions more flexible and reducing the cost of the renovation.
Application advantages
Internal voltage stabilization and regulation
The module automatically adjusts the input voltage to a standard 24 V DC output through its internal voltage stabilization circuit. Even if the input voltage fluctuates slightly, it will not affect the normal operation of the PLC, I/O mo,dule or auxiliary equipment.
Compatible with the power supply requirements of multiple devices
The DSSR122 Power Supply Unit outputs a stable voltage, providing a consistent power supply for different modules in the control system. Regardless of the source of the input, the output remains standardized. This capability ensures that all devices in the control cabinet can work safely and efficiently together.
Enhance system expansion flexibility.
During system renovation or expansion, both new power supplies and existing ones can be directly connected to the DSSR122 Power Supply Unit, without the need for re-designing the wiring or adding converters. This significantly reduces engineering renovation costs and construction complexity.
