RoentDek DLD40 - How to Switch the AC Supply Voltage

b) Connect the SPS1 power supply to the mains voltage. You will need a standard three-pole mains cord with protective
ground (IEC320/EN60320 C14 connector, rated at 250V 10A).
CAUTION
: Make sure to use only power outlets with a proper protective earth connection.
c) Connect your (N)DLATR6, (N)DLATR8 or ATR19 device to the SPS1’s output connector. You will need a 9-pin
Sub-D male-male cable with the following three pins connected 1:1.

Table 3.1: Pin assignments of the 9-pin Sub-D output connector
Do not use standard RS-232 cables or similar since they do not have the wire cross-section needed for the high output currents
of the SPS1. Only use cables with a cross-section of at least 0.75mm². Use shielded cables if possible.
CAUTION
: Do not connect any other devices than the RoentDek (N)DLATR6, (N)DLATR8, ATR19 (or CFD1b) to
the SPS1(b) before checking with RoentDek.
The SPS1 output is not short-circuit proof. If you short-circuit or overload the outputs, the internal fuses will have to be
replaced by new fuses of the same rating (250V F1.6A for positive output, 250V F2.5A for negative output. F=’flink’=quick
acting). You will have to open the casing for replacing the internal fuses. Make sure to disconnect the mains cord and the output
cable before opening the case!
Please note that in its standard configuration the
RoentDek ATR19 unit is equipped with an internal power supply. The
ATR19 does not automatically switch from this internal to an external power supply. If you bought an ATR19 device with
internal power supply and want to operate it using an external power supply like the SPS1, you will have to disable the ATR19’s
built-in power supply first (for details please refer to the ATR19 manual).

How to switch the AC supply voltage
The RoentDek SPS1 power supply can be switched between 100-125 and 200-250 Volts AC supply voltage range. Always
make sure that the supply voltage range is set correctly before connecting the mains voltage.
CAUTION
: Selecting the wrong input voltage may cause severe damage to the SPS1 power supply and/or the
attached devices!
In order to change the input voltage, remove the mains cord. Then simply slide the input voltage switch to the desired position.
The actual input voltage setting (‘115’ or ‘230’) will be shown. After that make sure to use the right input fuse before using the
SPS1 (see below).
use only:
100V AC
250V 0.63AT
(630mA slow blow = träge = T)
115-125V AC
250V 0.5AT
(500mA slow blow = träge = T)
200V AC
250V 0.315AT
(315mA slow blow = träge = T)
230-250V AC
250V 0.25AT
(250mA slow blow = träge = T)
Table 3.2: Used fuses
Use 250V fuses only. Fuse size must be Ø 5mm x 20mm.
CAUTION
: Never use the SPS1 with a fuse of a different rating than stated above! Never bypass the fuse!
