Phocos MPS80 Bedienungsanleitung Seite 22

With your new MPS Modular Power Switch, you own a state-of-the art device which was developed
according to the latest available technical standards. It comes with a number of outstanding features,
such as:
12, 24 or 48V (automatically detection)
Low voltage disconnect/load prioritization
Over-charge protection
Choose regulation between: pulse-width modulation, two-level-control, (or bank switching with
MCU)
Diversion control (dump loads) for wind and hydro power systems
Flexible grounding (negative or positive)
DIN rail mounting (possible to use with IP65 cabinet)
Five programmable voltage thresholds for load disconnect when used as a stand-alone unit.
More thresholds available when controlled by optional accessory MCU.
This manual gives important recommendations for installing, using and programming as well as
remedies in case of problems with the controller. Read it carefully in your own interest and mind
the safety and usage recommendations at the end of this manual.
Major Functions
Individual MPS units can be used as charge controller or load-controlling switch. A single MPS
unit can be used as an independent device within off-grid battery charging systems for lead acid
batteries. Also, multiple MPS units can operate within the same battery-based system with the
help of optional accessory MCU for more complex system designs.
MPS can be used to perform one of several tasks:
DC load control:
1. Load switch, positive/negative grounded
Battery charge control:
2. Panel switch, positive/negative grounded
3. Diversion load switch for battery charging via wind/hydro inputs. Diverts current from wind/hydro
inputs to a dump load resistor when battery is fully charged. To construct systems using multiple
MPS units, MPS has the ability to communicate with Phocos' Modular Central Unit (MCU) in order
to exchange system information and to program receive all necessary system settings (not object
of this manual).
There are two available MPS versions: MPS45 and MPS80.
The MPS controller automatically detects the nominal system voltage when connected to a 12V,
24V or 48V battery bank.
The MPS has a number of safety and display functions.
Recommendations for Use
The MPS controller warms up during normal operation. If there is insufficient ventilation (e.g.
in a cabinet), the controller has built-in overheating protection.
The MPS controller does not require any maintenance or service. Remove any dust with a dry tissue.
It is important that the battery bank achieves fully charged status frequently (at least once per
month). Otherwise the battery may be permanently damaged.
A battery can only be fully charged if the average energy consumption of all loads is clearly less
