1. Introduction
1-1. Introduction
The PSK-FB series power supply unit was developed for incorporation of the customer`s
device or machine. It is designed in compactness for making easier the power supply to
the mass flow meters / mass flow controllers manufactured by KOFLOC Corp. and for
easier providing of INPUT/OUTPUT signals to external appliances.
This power unit has a function to output +5V DC for power source of the flow indicator
in addition to those to output FLOW signals and to input FLOW SETTING signals to the
external appliances via the connection connector.

CAUTIONS:
・ APPLICATION OF THIS APPLIANCE AT THE STATUS EXCEEDING
THE SPECIFICATIONS CAUSES A MALFUNCTION THEREOF. IF NOT
AVOIDED, A CRITIAL FAULT OR ACCIDENT OF THE MOUNTED
DEVICE OR MACHINE MAY OCCUR.
2. Installation
2-1.In the case of receiving the product;
When receiving this product, fully observe the appearance and check to ensure that no
damages or breakages exist. If the packing is found to be abnormal, please instruct the
transporter to check for the status and contact us or our agent.
2-2.Installation
The installation posture has not been especially restricted. However, install the appliance
in a place where no powder dusts and water exist so as not to cause insulation fault
problems. If a temperature rise of the installation place is expected to be caused by the
ambient appliances is expected, pay particular attention to the installation environments
through installation of a cooling fan for improvement of the Ventilation. Avoid the
installation in a place where vibrations always occur, since it may cause a contact fault
accident of the cable connection unit.
CAUTIONS:
・Never install the meter in a damp or humid place. Hazard of
electric shock.
・Do not install the meter in a place where the ambient
temperature may rise excessively. Such a place will cause
the temperature of the internal circuit to rise and damage it.
・The installation of the meter in a place that is subjected to
vibration constantly may cause a contact failure of cable
connections.

2-3. Mounting
Securely mount this power unit on the mounting plate with reference to the outside
drawing in Fig. l. Form mounting, apply M3 small screws and consider the thickness of the
mounting plate to have a distance within 3mm to the main machine.
3. Wiring connection
3-1.Wiring connection with the mass flow controller (MFC) /
mass flow meter (MFM)
Connect the MFC or MFM to the 9P connector of this power unit with private purpose
cables corresponding thereto. When connecting the connector push-in it so that it mates
with the concavo-convex of the socket and pin units of the connector, and then tighten the
fixing thread on the cable side so as to prevent falling. See the attached connector shape
diagram and the standard schematics of model 3440 and 3660 mass flow controllers in the
attached Fig.1-4.
3-2 Wiring connection with the external appliances
Connect the external appliances to the 15P connector of this power unit with cables
applicable thereto. When connecting the connector, push-in it so that it mates with the
concavo-convex of the socket and pin units of the connector, and then tighten the fixing
thread on the cable side so as to prevent falling. See the connector shape diagram and the
standard schematics of model 3440 and 3660.mass how controllers in the attached Fig.1-4.

WARNING:
・APPLY PRIVATE-PURPOSE CABLES, OTHERWISF, A BREAK MAY
OCCUR.
CONNECTION WITH IMPROPER CABLES MAY DAMAGE POWER
UNIT, AND MFC / MFM.
PIN ARRANGEMENT OF D-SUB 9P CONNECTOR OF OUR PRODUCT
MODEL 3400 AND 3660 SERIES (MFC) IS IN CON- FORMITY WITH THE
SEMI-STANDAF.DS. PIN ARRANGEMENT OF D-SUB 9P CONNECTOR
OF MODEL 3750 SERTES (MFM) IS NOT IN CONFORMITY WITH THE
SEMI-STANDARDS.
ENSURE THAT CONNECTION CABLES OF MFC/MFM AND POWER
UNIT ARE PRIVATE-PURPOSE CABLES, THEN MAKE CONNECTION
WITH THEM.
FOR CONNECTION WITH EXTERNAL APPLIANCE CORRESP-
ONDING TO MFC OR MFM VIA POWER UNIT, BESURE TO MAKE IT TO
D-SUB 15P CONNECTOR CORRESPONDING TO D-SUB 9P CON-
NECTOR CONNECTED TO MFC / MFM.
4. Malfunction
4-1. In the case of a malfunction
If this power unit seems to have caused a malfunction, be sure to check for output
voltage on the safe portion such as the chip terminal of the connected appliance, not
with the connector pin of this appliance, so as to prevent short-circuit accidents.
If a malfunction occurs, contact us or our agent.
DANGER:
•NEVER PERFORM DISASSEMBLING.INTERNAL TOUCHING
MAY CAUSE AN ELECTRIC SHOCK, THUS RESULTING IN
A CRITICAL DANGER.
