EP120-PKIT | Parallel Kit for EP120 UPS System – Load Sharing & Redundancy

EP120‑PKIT — Parallel Kit for EP120 UPS

EP120‑PKIT is the parallel connection kit accessory designed to enable parallel operation of multiple EP120 series UPS units (such as the three‑phase 120 kVA UPS from the EP series). Parallel operation allows several UPS modules to work together as a single larger power system, offering increased capacity and redundancy.

Key Description

The EP120‑PKIT is a hardware accessory that enables:

• 🔌 Parallel operation of two or more EP120 UPS units — linking their inverter outputs so they operate in synchrony.

• 🔄 Load sharing and redundancy, meaning the total power capacity is increased and if one UPS fails, the others can continue supplying power without interruption.

• 📡 Communication and synchronization between UPS units — ensures they run in phase with each other.

It typically consists of communication modules, interface cards, and interconnecting cables that allow the UPS units to share status, control signals, and power coordination. (While specific manufacturer documentation for the EP120‑PKIT itself was not found online, this description matches standard UPS parallel kits used with large three‑phase UPS systems and is consistent with how EP120 UPSs are designed for parallel redundancy).

What It Does in Practice

When installed on multiple EP120 UPS units:

✅ The UPS units are synchronized in frequency and phase
✅ Loads are shared evenly across units
✅ Parallel control maintains balanced current output
✅ The system can operate in N+1 or N+X redundancy configurations

This is essential in data centers, industrial facilities, and critical infrastructure where uninterrupted power and system scalability are required.

Notes Before Purchasing

✔ EP120‑PKIT must be matched to the specific UPS model (EP120) — parallel kits are not universal.
✔ Installation is typically done by a qualified technician or installer.
✔ Without this kit, EP120 units may support parallel redundancy only in limited or manual configurations.
