POWER SYSTEM, OVERVOLTAGE CATEGORY & ENVIRONMENTAL CONDITIONS

The HFE1600-xy units have been evaluated for using in TT and IT (230VAC line - to - line) power systems. The HFE1600-xy units have been evaluated to Overvoltage category II. The HFE1600-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

HFE1600-xy units are Class I product. To minimize electrical shock hazard, the HFE1600-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 HFE1600-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: HFE1600-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 HFE1600-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 HFE1600-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.

HFE1600-xy unit fuse rating is described below. F101: F20A H 250Vac.

SICHERUNGEN

Vor Anschluss an die Netzversorgung ist die Aufstellanleitung zu beachten!

Absicherung: F1 01: F20A H 250VAC

Parallel Operation

Figure 4–1:

Parallel Connection

• Up to 10 x HFE1600 units with the same rating (voltage and current) can be used in parallel to increase the output current.

• By connecting the CS signal between the paralleled units, automatic current balance is achieved with accuracy of

Accuracy ±10%: 20% ≤ Iout < 50% of max Iout. Up to 10 units Accuracy ±5%: Iout ≥ 50% of max Iout. Up to 10 units.

• Derate the total output current by 5% when using parallel operation to prevent unit overload condition.

• The built-in O-Ring MOSFETs on the main output and the 12V Auxiliary output allow N+1 operation.

• If Voltage programming is used, "Voltage Programming” Pin of all units must be connected in parallel.

• Referenced to “SIGNAL RETURN” (floating from the output) controls/signals and +12V AUX can be connected in parallel.

• ENABLE of all supplies can be connected to a single switch.

For PMBus option.

• If voltage programming is done with PMBus, Voltage Programming and VREFERENCE OUT of all units must be connected in parallel.

• Connect PMBus Signals in parallel (PMBUS is isolated from output), and choose different address for each unit.

5.1.1 PMBus Interface

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

5.1.2 HFE1600 May Have Option al Pow e r M an age m en t Bu s Har dw are

The PMBUS interface in the HFE1600 (/S option) includes:

• Monitoring the Output Voltage, Current and Temperature.

• Programming the Output Voltage.

• 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.

ATTENTION:

If PMBus is used for voltage programming, the reference voltage will not be fixed to 5V but can be variable

(Reference voltage will be used for voltage 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 (A3, A2, A1, A0 Inputs)

Four variable address lines allow up to 16 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 3 Most Significant Bits A6, A5, A4 always equals 001. Variable part of address consists of 4 Least Significant bits: A3, A2, A1, and A0. Value of these four bits have to be assigned by hardware connections of 4 pins of the PS connectors. The Address lines (A3, 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 16 possible addresses: from 0010000 to 0011111.

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 - A3(J1.B10), A2(J1.B5), A1(J1.B14), A0(J1.B16) are not connected – ADDRESS 0011111;

Second unit - A0(J1.B16) is connected to -SENSE – ADDRESS 0011110;

Third unit – A1(J1.B14) is connected to -SENSE – ADDRESS 0011101;

ATTENTION:

A3, A2, A1, A0 signals and -SENSE are NOT isolated from the Output Terminals. Hot Plug: When hot plugging a power supply into a live system, the supply takes about 1-2 seconds to configure

It is address on the bus (based on the analog voltage levels present on the back plane).

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.

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.

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.
