PSP SAK-4-100MS-M Series Manual

SAK-4-100MS-M
Load Watch - Power Manager
Allows 4 loads up to 100A to be added to any main service panel or sub panel that is at risk of overload, or will become
overloaded, when a new load is introduced. The onboard intelligent micro-controller monitors the load on the existing
panel and only allows the added load access to the panel when capacity is available on each of the four existing loads.
Installation requires four open breakers or two quad breakers.

Features
4"
• Manages loads of 4 EV chargers up
to 100A each
• Can be installed on any main or
sub panel up to 400A to add managed
loads up to 100A continuous.
• Adapts to any application using the precision field
adjustable set points. These maximize access to the
added load and prevent looping.
• Field adjustable set points include: panel overload
amperage, overload inrush cutoff delay, restore
amperage threshold, load restore delay time and
line-loss compensation adjustment for CTs. Controller
LCD displays actual real-time amperage on panel.
• Controller is self-powered from line voltage. External
power supply not required. Can control 120 VAC
single pole or 208–240VAC double pole circuits.
• Prevents overloading and saves costly upgrades to
panel and/or electrical infrastructure.
• Utilizes a magnetic latching relay for long-term
reliability, and box-lug in and out terminals for ease
of installation.
• 2 year warranty
• Comes standard in NEMA 1 enclosure
(NEMA 3R option also available)

PROBLEM: Main circuit panel does not have
capacity to add EVC and trips main breaker
when EVC is active.
SOLUTION: Install SAK-4-100MS-M- in
between EVC and main panel. Load
management device will ensure panel is never
overloaded by EVC or any controlled load
connected to SAK-4-100MS-M.
PROBLEM: New load is required downstream
of main panel. The remote sub panel is near
capacity. It is not cost-effective to run new
circuit from main panel.
SOLUTION: Install SAK-4-100MS-M
in between EVC and sub panel. Load
management device will ensure sub panel is
never overloaded by EVC or any controlled
load connected to SAK-4-100MS-M.
