Siemens SITOP 6EP1931-2EC21 24VDC 15A DC UPS Module Industrial

Description

The Siemens SITOP 6EP1931-2EC21 DC UPS Module is a heavy-duty 24V DC uninterruptible power supply component built for industrial automation systems. Operating on a nominal 24V DC input (22–29V DC range), it supplies a steady 24V DC output at up to 15 Amperes.

When paired with external battery modules, this module buffers power dips and unexpected outages. It prevents system reboots, loss of operational memory, and costly manufacturing downtime.

In Bangladesh’s industrial sector—where grid voltage instability, brownouts, and sudden load-shedding are frequent—this DC UPS ensures continuous process control across automated plants.

Key Features

• 15A Rated Output: Provides continuous 24V DC / 15A output current for heavy-duty control panels.
• Compact DIN Rail Design: Measures 50 x 125 x 125 mm to save space inside control cabinets.
• Interface-Free Operation: Standalone module without integrated serial or USB interfaces for simple, reliable wiring.
• Dynamic Charging Management: Automatically charges external 24V battery modules to ensure system readiness.
• LED Status Indicators: Clear diagnostic LEDs for normal operation, battery operation, and fault conditions.
