TS1700/TK18 PRINTERS OPERATION MANUAL
4.3.
POWER SUPPLY
The TS1700 is powered by an external power supply by means of four pins of the shared
connector that is also used for RS232 communication, photo sensors and digital output. Although the
connector is polarized, if forced it could be connected inverted so it is very important to observe polarity
before plugging the connector in.

The power supply female connector must be a:
Housing:
PHDR-18VS
(JST Ref.)
Terminal:
SPHD-001T-P0.5
or equivalent.
Wire:
22 AWG
or thicker (GND & VIN)
NOTES:
(1) If the number of dots that are energized at the same time is increased, a higher current
will flow; therefore, a power supply with an adequate current capability must be used.
(2) When designing lines and bit images, take the printing ratio and print duty into
consideration. Print quality may be poor if the printing ratio (energizing pulses/dot line) or
print duty is high.
(3) Average energizing pulse width is defined as 64 of 192 dots/dot line that are energized.
WARNING: Beware not to invert the polarity of power supply. This may
irremediably damage the printer. Ensure that the voltage is the correct
one. Use the 4 terminals (4 wires) with 0.35mm² minimum section each.
NOTE ABOUT POWER SUPPLY:
The current demand depends on the density of the printout. A 60W power supply covers all
adverse possibility (see section
- ELECTRICAL SPECIFICATIONS
).
FENIX offers different power supplies as an accessory option (See APPENDIX
– HOW TO
ORDER
).
