POWER SYSTEM, OVERVOLTAGE CATEGORY & ENVIRONMENTAL CONDITIONS

The RFE1600-xy units have been evaluated for using in TT and IT (230VAC line - to - line) power systems.
The RFE1600-xy units have been evaluated to Overvoltage category II.
The RFE1600-xy units intended for use in the following operation conditions:
* Indoor use * Pollution degree 2 * Max. Operational altitude: 3000m above sea level
*Ambient temperature: -10°C-50°C at 100% load, up to 70°C with output de-rating applied (refer to Specification above).

GROUNDING

RFE1600-xy units are Class I product. To minimize electrical shock hazard, the RFE1600-xy units must be connected to an
electrical ground. The instruments must be connected to the AC power supply mains through a three conductor power
cable, with the ground wire firmly connected to an electrical ground (safety ground) at the power outlet. For instruments
designed to be hard- wired to the supply mains, the protective earth terminal must be connected to the safety electrical
ground before any other connection is made. Any interruption of the protective ground conductor or disconnection of the
protective earth terminal will cause a potential shock hazard that might cause personal injury.

Erdungskonzept

Dieses Produkt ist ein Gerät der Schutzklasse 1. Zur Vermeidung von gefährlichen Energieinhalten und Spannungen, ist
das Gehäuse an eine Schutzerde anzuschliessen. Der PE-Anschluss ist an einen festen Erder anzuschliessen. Bei
Festverdrahtung des Gerätes ist sicherzustellen, dass der PE Anschluss als erstes angeklemmt wird. Jede mögliche
Unterbrechung des PE-Leiters oder Trennung der PE Verbindung kann einen möglichen elektrischen Schlag
hervorrufen, der Personenschäden zur Folge hätte.

LIVE CIRCUITS

Operating personnel must not remove the RFE1600-xy unit cover.
No internal adjustment or component replacement is allowed by non-TDK Lambda qualified service personnel. Never
replace components with power cable connected. To avoid injuries, always disconnect power, discharge circuits and
remove external voltage sources before touching components.
Restricted Access Area: RFE1600-xy units should only be installed in a Restricted Access Area. Access should be available to
service personnel only.

Spannungsführende Teile

Die Geräteabdeckung darf nicht durch Endanwender geöffnet werden. Interne Modifikationen, sowie Bauteileaustausch
ist nur durch TDK-Lambda qualifiziertes Personal erlaubt. Vor Austausch von Bauteilen ist das Netzkabel bzw. die
Versorgungsspannung zu trennen. Energieversorgungsanschlüsse sind immer zu trennen, um Personenschäden durch
gefährliche Energieinhalte und Spannungen auszuschliessen. Die Stromkreise sind zu entladen, externe
Spannungsquellen sind zu entfernen, bevor auf Bauteile bzw. Komponenten Ebene gearbeitet wird.

PARTS SUBSTITUTIONS & MODIFICATIONS

Parts substitutions and modifications are allowed to authorized TDK Lambda service personnel only. For repairs or

modifications, the instrument must be returned to TDK Lambda service facility.

AC INPUT

Do not connect RFE1600-xv unit to mains supply exceeding the input voltage and frequency rating. The input voltage and
frequency rating is: 100-240V~, 50/60Hz. For safety reasons, the mains supply voltage fluctuations should not exceed
±10% of nominal voltage.

HEAT HAZARD

WARNING: Top, bottom and side surfaces may become hot when operating the unit continuously. To reduce the risk of

injury from a hot surface, allow the surface to cool before touching.

Heisse Oberflächen

WARNUNG: Im Dauerbetrieb erwärmen sich die Gehäuseoberflächen. Um das Verletzungs-Risiko durch heisse
Oberflächen zu minimieren, sollte das Gerät einige Zeit abkühlen können, bevor weitere Arbeiten durchgeführt
werden.

ENERGY HAZARD

The main output of RFE1600-xy units is capable of providing hazardous energy. Due to hazardous energy level the output

and connections therefore must not be user accessible. Manufacturer’s final equipment must provide protection to service

personnel against inadvertent contact with output bus bars.

FUSE

Internal fuse is sized for fault protection and if a fuse was opened it would indicate that service is required.

Fuse replacement should be made by qualified technical personnel.

RFE1600-xy unit fuse rating is described below. F101: F20A H 250Vac.

5.1.1 PMBus Interface Option

The communications bus signals are powered by an external 3.3V power source pulled up with a 1.5kΩ resistor.

5.1.2 RFE1600 May Have Optional Power Management Bus Hardware

The PMBUS interface in the RFE1600 (/S option) includes:

 Monitoring the Output Voltage, Current and Temperature.
 Programming the Output Voltage and Current.
 Programming the Maximum allowed output Voltage.
 Programming the Supply On/OFF.
 Reading and Clearing Faults.
 Reading the Manufacturing Related Data (Model Name, Serial No, Manufacturing Date, etc.).
 Storing the following conditions at AC Off.

- Set Output voltage.

- Max allowed programmable output voltage / Current limit (OCP).

ATTENTION:

If PMBus is used for voltage/current programming, the reference voltage will not be fixed to 5V but can be variable
(Reference voltage will be used for voltage/current programming).

The PMBUS supports:

 100 KHz Operation.
 Block Read Protocol.
 Group Command Protocol.

 Direct Data Format for Monitoring and Programming Functions.

5.1.3 Addressing (A2, A1, A0 Inputs)

Four variable address lines allow up to 8 Supplies to be connected on a single bus.
PMBus uses 7 bit addressing.
There is constant part of address and variable part of address:
Constant part of address consists of 4 Most Significant Bits A6, A5, A4 and A3 always equals 0010.
Variable part of address consists of 3 Least Significant bits: A2, A1 and A0.
Value of these four bits have to be assigned by hardware connections of 3 pins of the PS connectors.
The Address lines (A2, A1, and A0) are internally pulled up by resistors to +5V.
The address lines can be left open for ‹1› address or connected to -S for ‹0› address.
So, available Address Space contains 8 possible addresses: from 0010000 to 0010111.

In case more than one unit is connected to PMBus, each unit must be set to its own unique address.
Duplicate addressing is not allowed.

For example: First unit – A0(J2-1), A1(J2-2), A3(J2-3) are not connected – ADDRESS 0010111;

Second unit - A0(J2-1) is connected to -SENSE – ADDRESS 0010110;

Third unit – A1(J2-2) is connected to -SENSE – ADDRESS 0010101;

ATTENTION:

A2, A1, A0 signals and -SENSE are NOT isolated from the Output Terminals.

5.1.4 Serial Clock

This line is clocked by the Controller which controls the PMBUS. It should be connected to +3.3V
(Referenced to "Signal RTN") via a 1.5kΩ pull-up resistor.

5.1.5 Serial Data

This is a Bi-Directional line which must be connected to +3.3V (referenced to Signal RTN) via a 1.5kΩ pull up resistor.

19

5.1.6 SMB Alert

SMBALERT is used to indicate to the HOST about any Faults/Error Conditions.
This line must be connected to +3.3V (referenced to Signal RTN) via a 1.5kΩ pull up resistor.
This Signal is HIGH to indicate that no fault/error is present. If some fault/error occurs, the signal will go LOW.
The Host system must poll multiple supplies after receiving SMBALERT to retrieve fault/warning information.

5.1.7 PMBus Typical Connection

"SIGNAL RETURN" and PMBus signals are isolated from the Output terminals and Senses.

Figure 5–1: PMBus Typical Connection

PMBus Command Set

The interval between two consecutive commands to the power supply should be at least 25ms to ensure proper
monitoring functionality.

5.2.1 Read Status

This Command is used to read the status of the Power Supply. The Status information is stored in a special register
called the “STATUS REGISTER”. The PMBUS reads 8 different types of Faults and Warnings.

No 6 will be “1”, and SMBALERT will become “LOW”.
(*2) If any Command sent is not understood by the Supply, bit no 7 will be “1” and SMBALERT will become “LOW”.

5.2.2 Clear Faults

This command is used to clear the “STATUS REGISTER” after any fault occurs.
If the CLEAR_FAULTS command is not sent after any fault, the “STATUS REGISTER” will not be cleared.
SMBALERT signal will remain “LOW” until “CLEAR_FAULTS” command is sent.
If a Fault or Warning is still present after “CLEAR_FAULTS” is sent, “STATUS REGISTER” will be updated and the
SMBALERT signal will be “LOW” again.
