Please read this document very carefully to avoid DC/DC converter malfunction, equipment damage and/or fire hazards!
WARNING
!
Limitations of use: do not use in connection with life support systems or other medical equipment or devices. To be installed only by qualified technicians.
CAUTION
Introduc on
The TDCi-CH series are based on the standard TDCi products, but are equipped with an
automa c ba ery charging func onality. This enables the possibility to charge a ba ery
connected to the output from another ba ery connected to the input. The TDCi-CH models are
galvanically isolated, which means that the input and output circuits are not electrically
connected to each other.
Installa on
1) Check if the input voltage range of this model is compa ble with your DC source (ba ery or
power supply)
2) The TDCi-CH must be mounted in a cool, dry indoor loca on
3) For models with 12V/20A output use 4mm² cable size for both input and output wiring.
For models with 24V/10A output use 4mm² for input wiring and at least 2.5mm² for output
wiring.
4) Always install fuses at the input and output. If no fuses are used then warranty is void
5) First connect the nega ve input and output to the corresponding nega ve input and output
terminals of the converter. A en on: A bad nega ve connec on could make the output
voltage equal to the input voltage!
6) Now connect the posi ve input cable, via a suitably rated fuse, to the posi ve input terminal
7) Check if the output voltage of the unit meets the requirements of the ba ery to be charged.
When these requirements are met, you can now safely connect the ba ery to posi ve output
terminal through a suitably rated fuse.

Opera on
The TDCi-CH has three different modes: "Charge", "Standby" and "Off". Once connected, the
converter will be in the "Off mode". In this mode, the converter will output 0V and the yellow
(input) LED will flash once per second. The green (output) LED is off.
When the input voltage is above 11.8V (or 23.6V for 24V input model) for at least 5 seconds, the
converter will automa cally jump to the "Charge mode". In this mode the converter supplies
14.4V (or 28.8V for 24V output model) and both the yellow (input) and the green (output) LEDs
are on.
When during the charge process the ba ery (output-) voltage has reached 14.2V (or 28.4V for
24V output model), a mer will start that will run for one hour. A er one hour, the converter will
jump to the "Standby mode". In this mode the output voltage will be set to 13.7V (or 27.4V for
24V output model) and both the yellow and green LEDs are lit.
The TDCi-CH will restart this charge process again when:
- The output voltage drops below 13.2V (or 26.4V for 24V output model) for 5 seconds.
- Or when the TDCi-CH has been in the "Standby mode" for 24 consecu ve hours.
During opera on in the "Charge mode" or "Standby mode", the TDCi-CH will automa cally jump
to the "Off mode" when:
- The input voltage drops below 11.6V (or 23.2V for 24V input model) for 10 seconds.
- Or the input voltage drops below 11.8V (or 23.6V for 24V input model) for 5 minutes.
