Introduction
The Güralp Portable Power Module, or PPM, is a convenient charge-control and
battery system that can provide continuous power to a Güralp Fortimus or Certimus
instrument in a solar-powered installation. It can also be used a stand-alone battery
for short-term, off-grid Fortimus or Certimus deployments.
When used with solar panels, the integrated charge controller operates on the MPPT
(Maximum Power Point Tracking) principle and will automatically adjust its input
impedance to draw the maximum power from the connected solar panel, regardless
of changes in light conditions.
The Portable Power Module is a single, rugged, sealed unit and is supplied with:
•
an output cable for connecting it directly to the Fortimus or Certimus. This
cable has a four-pin bayonet connector on each end.
•
a charge cable. This connects to the PPM via a six-pin bayonet connector and
is terminated at the other end in a pair of industry standard MC4 connectors.
Note:
The PPM has a sleep mode, during which no power output is
provided. This is known as "hibernation". It is shipped in this mode and
must be "awakened" before use: see section 4.1 on page 7 for details.
