Product Overview

The Pentair IntelliChlor Power Center EC-520556 supplies the electrical power required to operate compatible Pentair salt chlorine generator cells. Also known as the PC100 Power Center, it converts incoming AC electrical current into the low-voltage DC power used by the electrolytic cell to produce chlorine from salt in the pool water.

This power center is designed for equipment-pad installation and can be connected to compatible Pentair automation systems through an RS-485 communication connection. The salt cell, plumbing unions, automation controller, and installation materials are not included unless specifically stated.

Specifications

The power center must be wired so the connected salt cell operates only when the circulation pump is running. Input-voltage configuration must match the available electrical supply.

Installation Information

Installation must be completed by a qualified pool professional or licensed electrician. Before installation, verify the incoming voltage, breaker capacity, grounding, bonding, timer or automation wiring, circulation-pump interlock, and compatibility with the existing salt cell.

The enclosure should be installed in accordance with Pentair instructions and all applicable electrical and pool codes. Never energize the salt cell without proper water flow.

Confirm Before Ordering

• Confirm that the power center is the failed component.
• Verify the salt cell model is compatible.
• Confirm the required incoming voltage.
• Check the existing power center part number.
• Verify automation communication requirements.
• Note that the electrolytic salt cell is not included.
• Inspect the cell cable and connector for damage.
• Confirm professional installation is available.
• Do not order this product as a complete salt system.

Pentair’s newer IntelliChlor Plus and LT replacement cells remain compatible with existing IntelliChlor power centers, providing an upgrade path for many legacy systems.

Warranty Information

This power center is covered according to Pentair’s applicable limited-warranty terms. Coverage may depend on authorized-dealer purchase, professional installation, proof of purchase, correct voltage, proper grounding and bonding, and compliance with Pentair instructions.

Damage caused by incorrect voltage, improper wiring, electrical surges, water intrusion, corrosion, flooding, or unauthorized modification may not be covered.

Customer Q&A
