2. Product introduction

The YOKOGAWA SPW482-13 S1 is a specialized industrial redundant power supply designed to deliver stable 48V DC power to medium-scale automation systems requiring higher voltage than 24V solutions. Unlike the 24V-focused SPW481-53, this module caters to equipment like communication switches, motor drives, and high-power sensors, serving as a reliable energy source for systems where 48V is the standard (such as the ISC40G-TF-T1-05 Ethernet switch and certain S2BN5D-121 DO modules in high-power configurations).

With a total output current of 20A (10A per channel in dual output mode), the SPW482-13 S1 balances power and efficiency, making it suitable for distributed systems with multiple 48V devices. It supports seamless switching between AC and DC inputs, ensuring uninterrupted operation during power source transitions. The module’s enhanced efficiency (≥93%) and tighter regulation (±0.3%) guarantee stable voltage for sensitive 48V components, critical for industries like telecommunications, renewable energy, and intelligent transportation systems. As a dedicated 48V power solution, the YOKOGAWA SPW482-13 S1 ensures consistent performance of higher-voltage industrial equipment, reducing the risk of malfunctions caused by voltage instability.

3. Core advantages and technical highlights

48V specialized power delivery:

Optimized for 48V devices, the SPW482-13 S1 outperforms the 24V SPW481-53 in systems requiring higher voltage. In a 5G base station’s industrial control system, it powers 48V radio frequency (RF) amplifiers and cooling fans, where using a 24V supply would require step-up converters that introduce inefficiency and noise. This direct 48V output eliminates conversion losses, improving overall system efficiency by up to 8% compared to 24V-based setups.

Enhanced regulation for voltage-sensitive equipment:

With ±0.3% line and load regulation (tighter than the SPW481-53’s ±0.5%), the SPW482-13 S1 maintains stable output even during rapid load changes. In a solar inverter control system, it powers 48V communication modules that transmit real-time performance data to the SCP401-11 PLC. The precise regulation prevents data corruption caused by voltage fluctuations, ensuring accurate remote monitoring of solar panel efficiency.

Extended temperature resilience:

Operating from -20°C to 75°C (wider than the SPW481-53’s range), the SPW482-13 S1 thrives in extreme environments. In a railway traction system’s control cabinet, it withstands subzero temperatures in winter and high ambient heat from nearby motors, ensuring 48V door control mechanisms and status sensors (connected to SNB10D-425/CU2N modules) remain operational regardless of external conditions. Its conformal coating also protects against moisture and dust in tunnel environments.

Hot-swap capable redundancy:

Unlike the SPW481-53, the SPW482-13 S1 supports hot-swap in 1+1 redundant configurations, allowing module replacement without powering down connected equipment. In a data center’s industrial cooling system, technicians can replace a faulty unit while the redundant module continues powering 48V variable-speed pumps, preventing cooling interruptions that could damage servers. This feature reduces maintenance downtime from hours to minutes.

4. Typical application scenarios

In a smart grid substation, the SPW482-13 S1 powers 48V protective relays, communication gateways, and SNB10D-425/CU2N modules monitoring breaker statuses. Its 48V output directly matches the substation’s standard 48V battery backup system, enabling seamless 切换 between grid AC and battery DC during outages. The tight regulation ensures protective relays operate within precise voltage tolerances, critical for preventing false tripping during power grid disturbances.

In an electric vehicle (EV) charging station, the module supplies 48V to charging pile control boards, RFID readers, and S2BN5D-121 DO modules managing contactors. Its dual-input design allows operation from both the grid AC and a backup generator, ensuring charging stations remain functional during blackouts. The hot-swap capability means maintenance can be performed without interrupting active charging sessions, improving service availability.

In a wind turbine’s nacelle control system, the SPW482-13 S1 powers 48V pitch control actuators and vibration sensors (connected to SAI533-H33 modules). Its wide temperature range handles the extreme cold of high-altitude operation, while the redundant design ensures the pitch system can still feather the blades safely if one power supply fails, preventing turbine damage during storms.

6. Installation, commissioning and maintenance instructions

Installation preparation

Mount the SPW482-13 S1 in a control cabinet with at least 150mm clearance for ventilation, ensuring ambient temperature stays within -20°C to 75°C. Use a torque wrench (2-4Nm) for terminal connections, and verify input compatibility with either 85-264V AC or 110-300V DC.

Install 6mm² cables for output connections to handle 20A current, with separate runs for each channel. In redundant setups, connect two modules to the RBPW-03 hot-swap module, ensuring input sources are isolated (e.g., primary AC and backup DC) for maximum reliability. Ground the unit with a 4mm² wire to the cabinet’s PE busbar, and label input/output lines clearly to avoid polarity errors during maintenance.

Maintenance suggestions

Perform monthly visual checks for loose connections, dust buildup, or fan irregularities. Clean ventilation ports with compressed air monthly in dusty environments (e.g., wind turbine nacelles) to prevent overheating. Monitor output voltage weekly using a precision multimeter, ensuring it remains within 48V ±0.3%.

Test hot-swap functionality quarterly by removing one redundant module while the system is active, confirming the second unit maintains uninterrupted power to connected devices like the ISC40G-TF-T1-05 switch. Replace fans annually as preventive maintenance, and calibrate voltage regulation circuits every two years to preserve ±0.3% accuracy.

Use the module’s diagnostic interface to log fault codes (e.g., overcurrent events) and correlate them with connected equipment status via the SCP401-11 PLC. This helps identify whether issues stem from the power supply or devices like overloaded S2BN5D-121 DO modules.
