Specifications
MECHANICAL
Intervolt SVCi Series isolated switchmode voltage converters have been developed
to withstand demanding applications. The extruded case is manufactured from
marine grade aluminium and provides excellent mechanical strength and heat
dissipation. All external fasteners are supplied in stainless steel, including
the terminal screws. The end caps are produced from a temperature resistant
plastic alloy, which has excellent impact strength. The fascia panel is produced
in scratch resistant polycarbonate and is reverse printed to prevent long-term
degradation. Internally the PC board is conformally coated to reduce the risk
of component corrosion. All heavy components are adhered to the PC board to
resist vibration damage.
ELECTRICAL
Intervolt SVCi Series isolated switchmode voltage converters are designed
for reliability, durability and longevity. The SVCi case is ungrounded therefore
ensuring electrical isolation. They are fully protected against incorrect
connection and/or application by a range of built-in safety devices. These
devices protect the unit from reverse connection, short circuit connection,
under voltage, overload and high temperatures. The equipment being operated
is protected from over voltage, surges and spikes. Microprocessor controlled
diagnostics indicate, via a tri-colour LED, the status of the unit (see features
for full description). Heavy-duty tin plated terminals provide simple, trouble
free termination.
PERFORMANCE
Intervolt SVCi Series switchmode voltage converters display excellent performance
characteristics. They have been designed to produce continuously heavy currents
under severe operating conditions, in particular at high temperatures. An
exacting specification and smart design has resulted in outstanding efficiency,
even under heavy loads (see graph). Voltage output is extremely well regulated,
up to and including the maximum rated load. The current draw in standby mode
is negligible. As a result units do not need to be manually switched, which
eliminates the need for a separate control wire. Output ripple is minimal
thus providing a clean, filtered supply, which meets the relevant Australian
standard for EMC requirements. Maximum current ratings are generous and practical
and are a key performance feature. Much of this specification has been achieved
through rigorous R & D, including the design and manufacture of purpose
built components. All units are 100% function tested as standard quality control
procedure.
