Electrical Requirements & Power Pack Configuration

Should you go with an individual or centralized power pack? The answer affects redundancy, maintenance downtime, and your electrical layout.

Design Decision

Should I go with an individual or centralized power pack?

Every hydraulic stacker needs a power pack to generate lifting pressure. The question is whether each unit should have its own dedicated power pack, or whether one larger unit should distribute hydraulic pressure through shared lines to multiple stackers.

The right solution depends on project priorities such as redundancy, maintenance access, space planning, and system efficiency.

Data Sheet

Base electrical specs per unit

From the APS 2PK6.0 product data sheet — these specifications apply to each individual stacker unit.

2.2 kW
Power unit required for each stacker.
208 V
3-phase, 60Hz electrical supply.
8.3 A
Working current during normal operation.
24 V
Control power for system operation.
System Architecture

When one thing breaks, what stops working?

A single hydraulic leak. Two architectures. The blast radius is the difference between a quick service call and a full garage shutdown.

Scenario
Higher Risk

Centralized

One pump. One shared line. One point of failure.

LEAK PUMP
0 5/5
stackers offline

A leak anywhere in the shared line can take every connected unit offline.

VS
Recommended

Individual

Five units. Five power packs. No shared failure point.

0 1/5
stackers offline

Each stacker has its own self-contained power pack. A failure stays local while the other units keep running.

Power Pack Analysis

The truth about power requirements.

Individual power packs do not require more total electrical power. The difference is how the same power is distributed — and what keeps running when one unit fails.

Exhibit B

Leaks create stains, slippery floors, downtime, and cleanup issues.

The Misconception
Myth

Individual power packs require more total electrical power.

Truth

Both systems draw the same total power from the grid. The real difference is how power is routed.

Operational Reality
3–5

valet attendants per floor max

Only enough lifts need to run at one time to serve the attendants on duty. Design power distribution around active use — not the total lift count.

Key Takeaway

Individual power packs provide greater reliability, easier maintenance, cleaner installation, and lower long-term risk.
