3.10.3 Remote sensing
Use remote sense where the load regulation at the load end is critical. In remote sense, the power
supply will compensate for voltage drop on the load wires. Refer to the power supply specifications
for the maximum voltage drop on load wires. The voltage drop is subtracted from the total voltage
available at the output. Follow the instructions below to configure the power supply for remote
sensing:
1. Ensure that the AC On/Off is in the Off position.
2. Remove the local sense jumpers from J2.
3. Connect the negative sense lead to terminal J2-5 (-S) and the positive sense lead to terminal
J2-1(+S) of the J2 mating connector. Ensure that the J2 mating connector is plugged securely
into the rear panel sense connector, J2.
4. Turn On the power supply.
- J2 connector type: MC 1.5/5-G-3.81, Phoenix.
- Plug type: MC 1.5/5-ST-3.81, Phoenix.
- Wire AWG; 28 up to 16.
- Stripping length: 7mm.
- Tightening torque:1.95-2.21Lb-Inch. (
To ensure safe transportation of the instrument, contact the Lambda sales or service facility near
you for Return Authorization and shipping information. Please attach a tag to the power supply
describing the problem and specifying the owner, model number and serial number of the power
supply. Refer to Warranty Information for further instructions.

0.22- 0.25Nm)
When using shielded sense wires, ground the shield in
one place only. The location can be the power supply
chassis or one of the output terminals.
Notes:
1.If the power supply is operating in remote sense
and either the positive or negative load wire is
not connected, an internal protection circuit will
activate and shut down the power supply. To
resume operation, turn the AC On/Off to the Off
position, connect the open load wire, and turn
On the power supply.
2.If the power supply is operated without the
remote sense lines or local sense jumpers, it will
continue to work, but the output voltage
regulation will be degraded. Also, the OVP
circuit may activate and shut down the power
supply.
WARNING
There is a potential shock hazard at the sense point
when using power supply with a rated output voltage
greater than 50V. Ensure that the connections at the
load end are shielded to prevent accidental contact
with hazardous voltages.
CAUTION
VORSICHT
WARNUNG
An den Anschlüssen für die Sense-Leitungen besteht
bei Stromversorgungen mit einer
Nennausgangsspannung von mehr als 50V die
Gefahr eines elektrischen Schlags. Stellen Sie sicher,
dass die Verbindungen an der Last gegen
versehentliches Berühren bei gefährlichen
Spannungen isoliert sind.
Wenn Sie abgeschirmte Sense-Leitungen
verwenden, erden Sie die Abschirmung nur an einer
Seite. Dies kann entweder das Gehäuse des
Netzteils oder eine der Ausgangsklemmen sein.
Hinweise:
1.Wird das Netzteil mit " Remote-Sensing" betrieben
und entweder das negative oder das positive
Lastkabel ist nicht angeschlossen, schalted das
Netzteil ab. Um den Betrieb wieder aufzunehmen,
schalten Sie den Netz-On/Off-Schalter auf "Off" ,
verbinden das Lastkabel und schalten das Netzteil
wieder ein.
2.Wenn das Netzteil ohne die Remote-Sense -
Leitungen betrieben wird oder der Jumper J2 für
lokales Sensing offen ist, arbeitet das Netzteil weiter,
allerdings mit einer verminderten Regelgenauigkeit
der Ausgangsspannung. Zudem kann der
Überspannungsschutz OVP auslösen und das Netzteil
abschalten.
