Description

The most outstandingfeatures of the 1606-XLS960E-3

DIN rail power supply are its extremely high

efciencies and its small size, which are achieved by a

synchronous rectication and other technological

breakthroughs.

Large power reserves of 150% support the startingof

heavy loads such as DC motors or capacitive loads. In

many cases this allows the use of a unit from a lower

wattage class which saves space and money.

High immunity to transients and power surges as well as

low electromagnetic emission allow the use of these

power supplies in nearly every environment.

The integrated output power manager, the three input

fuses and near zero input inrush current make

installation and usage simple. Diagnostics are easy due

to the DC-ok relay, a green DC-OK LED and the red

overload LED.

A large international approval package for a variety of

applications makes this unit suitable for nearly every

application.

1. Intended Use

•This device is designed for installation in an enclosure and is intended for the general professional use such as in industrial control, office,

communication, and instrumentation equipment.

•Do not use this power supply in equipment where malfunction may cause severe personal injury or threaten human life.

•This device is designed for use in non-hazardous, ordinary or unclassified locations.

2. Installation Requirements

•This device may only be installed and put into operation by qualified personnel.

•This device does not contain serviceable parts. The tripping of an internal fuse is caused by an internal defect.

•If damage or malfunction should occur during installation or operation, immediately turn power off and send unit to the factory for inspection.

•Mount the unit on a DIN rail so that the output and input terminals are located on the bottom of the unit. For other mounting orientations, see

derating requirements in this document. Refer to section 25.13.

•This device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do not cover ventilation grid

(e.g. cable conduits) by more than 30%!

•Keep the following installation clearances: 40mm on top, 20mm on the bottom, 5mm on the left and right sides are recommended when the

device is loaded permanently with more than 50% of the rated power. Increase this clearance to 15mm in case the adjacent device is a heat

source (e.g. another power supply).

SHOCK HAZARD: Do not use the power supply without proper grounding (Protective Earth). Use the terminal on the input

block for earth connection and not one of the screws on the housing.

- Turn power off before working on the device. Protect against inadvertent re-powering

- Make sure that the wiring is correct by following all local and national codes

- Do not modify or repair the unit

- Do not open the unit as high voltages are present inside

- Use caution to prevent any foreign objects from entering the housing

- Do not use in wet locations or in areas where moisture or condensation can be expected

- Do not touch during power-on, and immediately after power-off. Hot surfaces may cause burns.

WARNING: EXPLOSION HAZARDS!

Substitution of components may impair suitability for this environment. Do not disconnect the unit or operate the voltage adjustment or S/P jumper unless

power has been switched off or the area is known to be non-hazardous.

All parameters are specified at 24V, 40A, 3x400Vac, 25°C ambient and after a 5 minutes run-in time, unless noted otherwise.

*) BonusPower, short term power capability (up to typ. 4s)

The power supply is designed to support loads with a higher short-term power requirement without damage or shutdown. The short-

term duration is hardware-controlled by an output power manager. BonusPower is repeatedly available. Detailed information

can be found in section 25.1. If the power supply is loaded longer with the BonusPower than shown in the bonus-time diagram (see

Fig. 6-3), the max. output power is automatically reduced to 960W.

**) Discharge current of output capacitors is not included.

***) This is the maximum output voltage which can occur at the clockwise end position of the potentiometer due to tolerances. There is no

guarantee that this value can be achieved. The typical value is about 28.5V.

All parameters are specified at 24V, 40A, 3x400Vac, 25°C ambient and after a 5 minutes run-in time, unless noted otherwise.

8. DC OK Relay Contact

This feature monitors the output voltage, which is produced by the power supply itself. It is independent of a back-fed

voltage from a unit connected in parallel to the power supply output.

Contact closes As soon as the output voltage reaches 90% of the adjusted output voltage.

Contact opens As soon as the output voltage dips more than 10% below the adjusted output voltage.

Short dips will be extended to a signal length of 250ms. Dips shorter than 1ms will be ignored.

Contact re-closes As soon as the output voltage exceeds 90% of the adjusted voltage.

9. Shut-down Input

This feature allows a switch-off of the output of the power supply with a signal switch or an external voltage. The

shut-down function ramps down and has no safety feature included. The shut-down occurs immediately while the

turn-on is delayed up to 350ms. In a shut-down condition, the output voltage is <2V and the output power is <0.5W.

The voltage between different minus pole output terminals must be below 1V when units are connected in parallel. In

a series operation of multiple power supplies only wiring option “A” with individual signal switches is allowed.

Please note that option C requires a current sink capability of the voltage source. Do not use a blocking diode.

10. Remote Control of Output Voltage

The shut-down input can also be used to remotely adjust the output voltage between typically 14Vdc and 28Vdc. All

other functions of shut-down input remain the same.

The control voltage is referenced to the main ground (negative output voltage).

Instructions:

1. Set the unit into “Single Use” mode.

2. Set the output voltage adjustment (24-28V) to the maximum desired voltage.

3. Apply a control voltage to reduce the output voltage.

11. Internal Data Logging

A protected microcontroller inside the power supply acquires and stores operating data during the life of the unit. The

data can be downloaded with a small tool and special software by Rockwell Automation service and repair personnel,

even if the unit is faulty. Having the data facilitates troubleshooting. Knowledge of the events occuring just before a

failure allows for a more accurate analysis of the problem.

The data will be acquired with a xed sampling rate unless the peak detectors trigger due to an abnormal condition.

In such cases, the abnormal condition is properly captured.

Acquired data:

- Family name of unit (1606-XLS), revision of rmware

- Operational hours and expired portion of lifetime

- Operational data; latest 60 values with timestamps of the last 158 minutes of:

Number of over-voltage transients,

Average input voltage,

Peak input voltage,

Inside temperature,

Overloads > 2s,

Missing of one input phase (minimum output load required)

- Failure data; various errors such as:

Internal errors,

Over-temperature shut-down,

OVP,

Long-term overloads,

Remarkable temperatures inside the unit,

….

- Number of turn-on sequences and overvoltage transients
