Why is a 15V supply needed when most modules use 24V?
Certain legacy sensors, specialized I/O modules, and high-precision analog instruments require a stable 15V reference. The SPS03-15V ensures these components receive reliable power without introducing signal errors.
Can the SPS03-15V be used in redundant setups?
Yes. It is compatible with power assemblies designed for load-sharing or redundancy, allowing continuous operation even if one module fails.
Does the module provide protection against EMI and power surges?
Yes. The module’s internal shielding, high-quality inductive components, and built-in protection circuitry guard against EMI, over-voltage, and over-current conditions.
