Sentry HPS
SENTRY HPS HM/HT provides
maximum protection for vital ‘mission-
critical’ networks, security applications
(electro-medical) and industrial
applications thanks to its outstanding
mechanical and electrical design.
The load is powered continuously by
the inverter with a filtered, stabilised
and regulated sinewave supply. The
input and output EMI filters
considerably increase the immunity of
the load to mains disturbances and
surges.
The SENTRY HPS HM/HT series uses
on-line double conversion technology
(VFI) with an isolation transformer on the
inverter output.
SENTRY HPS HM/HT is supplied with
Watch&Save 3000 software as
standard and can be remotely
monitored using the PowerNetGuard
system from anywhere in the world.
Additional battery extension packs
allow the standard battery runtime to be
extended up to several hours.
MINIMUM IMPACT ON SUPPLIES -
EASY SOURSE
Input current distortion <4% for the
Sentry HPS with filter with sinusoidal
absorption to remove the risk of
resonance with other input supply
users or phase shift capacitor sets. The
absorbed current distortion is
independent of input supply
parameters such as impedance.
This enables Sentry HPS to deliver
maximum performance levels
regardless of the installation
environment. With these input features
Sentry HPS can achieve significant
savings in terms of sizing and power
supply sources - isolation transformers
and generators over less sophisticated
power systems.
MAXIMUM BATTERY CARE
• Battery deep discharge protection
• Temperature compensating charger
• Built-in automatic and manual battery
test feature
66
SIMPLE TO INSTALL
• Capability to install the UPS into any
distribution system (neutral not
required on rectifier input)
• Capability to separate the
rectifier/bypass power networks and
to power these from two separate
sources, without Galvanic isolation
(necessary on UPS without an output
transformer)
HIGH RELIABILITY
• Extremely high short-circuit current to
ensure compatibility with the most
difficult transformer applications
(lighting, drives and industrial
processes) and an isolation
transformer on the inverter output
• Full microprocessor control with
no-break static and manual bypasses
• IGBT technology
