PS4 Series

Easy & Optimized Assemblywith Plug-in Connection

Features:◗ Plug-in connection to improve efficiency and safety of assembly, maintenance, and unit expansion works◗ Floating design to absorb mounting misalignment ±2mm in XY direction◗ High current support: 150 Amps (supported busbar thickness 3mm or 0.125 inch (3.175mm) 300 Amps (supported busbar thickness 6mm or 0.25 inch (6.35mm)◗ Compact design applicable to 1U size◗ Multiple contact points on power contact decrease heat generation by current flow◗ Safety design in consideration of deterioration of resin over time◗ Large effective mating length reserves sufficient design margin of a unit◗ UL/C-UL/TÜV pending

Busbar Plug-in Connector Supporting 150 Amps/300 Amps with Floating Capability

Plug-in to busbar

Workload (assembly, maintenance, expansion) Plug-in mating largely reduces working hours Highly reliable connection is ensured regardless of operator’s skill

SafetyOperator does not need to touch the conductor, which improves safety

CONNECTOR’S BENEFITSAGAINST SCREW-TIGHTENING

Connector is ready to float.

FLOATINGSTRUCTURE

Initial state

After inserting

busbar

Connector horizontally shifts

(floats to align with the busbar) and is fixed.

Once the busbar is inserted,

the connector will: 1. rotate in direction. 2. apply contact pressure

in direction and be fixed.

Fixed

At this stage, contact pressure is not applied on the busbar.

Connector floats to the most appropriate matingposition where it aligns with busbar.
