SecureStart
module
for Copeland® compressors
Start-up performance and protection you can count on
Emerson’s SecureStart module uses state of the art technology to provide a safe and consistent start-up for the
compressor. By limiting the starting current by up to 75%, compressor start characteristics are improved and
nuisances caused by current variations are reduced. The SecureStart module delivers a new level of protection
and start-up consistency, providing reliable system performance and longevity.

Why use the SecureStart module?
How it works
Upon start-up, electric motors consume large amounts
of current as they accelerate and build a magnetic fi eld.
Starting currents may reach fi ve to eight times the levels
of nominal operating currents (see Figure 1). The
SecureStart module dramatically reduces the in-rush
current and renders light fl icker nearly imperceptible.
Additional benefi ts
• Improved starting during low voltage conditions
• Compressor low voltage protection
• Compliance with certain local utility requirements
for reduced in-rush current
• Reduced stress and heating of compressor
• Can reduce the HP required in mobile power generation
Once installed, the SecureStart module will detect and
reduce run winding current while adjusting the start
winding current to provide optimal starting torque. The
module provides an additional benefi t of continuously
monitoring supply voltage to prevent motor stalling
under low voltage conditions. When conditions such as
low supply voltage or locked rotor exist, the module will
switch off the motor, thereby protecting the compressor.
A delay function provides additional protection in the
event of an emergency shutdown.
SecureStart modules are designed for use with permanent split capacitor, single phase compressors with Rated
Load Amps (RLA) of 32 or less. SecureStart can be used
with Copeland
®
compressors designed for pool heaters,
mobile power generators, or geothermal applications.
The corresponding Copeland
®
compressors are listed
below in Table 1.
