Programmable Switch Mode Power Supplies

PS1600 Series

Compact 1 U size

Fast transient response

High slew Rate

Interface RS232, RS485, USB

Models with Output Voltage 16V to 1000 V, 1600 W Power

Ethernet (LAN) Optional

The PS1600 series power supplies is designed for compact 1 U size with user friendly operation and higher

efficiency. This range offer multi ranging output characteristic which makes them more flexible than traditional

or rectangular output characteristic power supplies as they give multiple voltage and current combination in a

single power supply.

This series of power supplies offer fast up programming time allowing creation of multiple complex waveforms.

Transient response better than 100 us, ensures that the output of the power supply recovers much faster and

remains constant and oscillation free for dynamic loads.

Power supplies can be remotely controlled programmed through any of interface analog programming , USB,

RS232 or RS485. Power supplies can be programmed from 0 to full scale voltage and current. SCPI

compatible commands offer flexibility in programming in system integration. Power capabilities can be added

by connecting four power supply units in parallel or in series up to 600V.

With various protection features, over voltage protection, short circuit protection, fold back etc. protects

expensive loads circuits in testing. Fold back protection allows to set precise maximum current to be allowed,

which when exceed output gets disabled. User selectable last save memory, allows user to quickly start the

testing from previous test conditions.

This power supply unit works on line voltage from 195 to 270 V, 47 Hz ~ 63 Hz. Power factor correction also

provides to ensure low harmonic content.

Grounding

The instrument ground must be well connected to instrument chassis of AC power mains input supply.

The instrument must be connected through three conductor power cable, with the ground wire firmly

connected to the electrical safety ground of power outlet. Any interruption in protective ground

conductor , or disconnection will cause potential hazard that might cause personal injury.

Mains Input rating

This power supply unit is designed for specific mains input connections, as specified in the Technical

specifications. Do not use AC supply exceeding the limits. For safety reasons the mains AC may

should not fluctuate more than 10 % of nominal voltage.+

Fuse

Fuses must be changed by authorized Scientific service personal only for continued

protection against risk and safety.

Live circuits

There are no serviceable part or alignment required by Operating personnel. Operator must not

remove the instrument cover. No internal adjustment or component replacement is allowed by non-

Scientific authorised qualified personnel. Never replace components with power cable connected. To

avoid injuries, always disconnect power, discharge circuits and remove external voltage source before

touching components.

2.4 Connection diagram for interface cables used

To connect the power supply unit for remote control, the connecting cable wiring diagram is given below.

2.4.1 USB Cable

This is a standard USB cable connector type A to type B, used for connecting power supply to host ( computer

or others). This is supplied as standard accessories with the unit.

2.4.2 RS232/RS485 Cable

This is cable is end User specific depends on the connections to remote units, panels etc. One end of this cable

is RJ45 (male) and other end is DB 9 ( Female) connector. User can assemble it as per their required length,

not more than 9 meter. Also available as optional accessories from Scientific.

2.4.3 Analog programming cable

This is cable is end User specific depends on the connections to remote units, panels etc. To prepare cable,

you will need standard DB 25 (male) connector, which connects the power supply rear panel at Analog

programming connector, DB 25 ( Female) connector. Depending on the required connection any good quality

multi core shielded cable can be use. For pin details please refer Analog programming in chapter 4 for

connections.

2.4.4 Master - Salve cable

For connecting power supplies in Master-Slave , use short length standard RJ45 to RJ45 ( 1:1 wired) cable.

Chapter 3 Installation

Your instrument is thoughtfully designed, manufactured, tested and inspected, found free of mechanical and

electrical defects. When you receive the instrument, some inspections are necessary, and the condition must

be understood and available before installing the instrument. Inspect the shipping container for damage if any

after unpacking it. It is not recommended to use the instrument in the case of a damaged container. Keep all

packing material until the inspection has been completed. If damage is detected, file a claim with carrier

immediately and inform the Dealer ,sales or authorized service facility nearest to you or Scientific.

If the contents in the container do not conform to the packing list, notify us or your dealer. Before putting this

instrument in operation, make sure you go through the manual, safety and Cautions guidelines.

Ensure that the environmental conditions are fulfilled. Ensure that the instrument is not be used in place with

vibrations, heating or exposed to sky , direct sunlight, for proper functioning and extensive life of service.

3.1 AC input mains connections

The mains AC socket ( IEC compatible ) is provided on the rear panel. Use the mains cord provided with the

instrument , alternative ensure appropriate rating cable is used for connections as per the standard mains cord

used in your country. This power supply unit is designed for 195 to 270 V , 47 ~ 63 Hz.

3.2 Cooling

The power supply unit is forced air cooled, it has two

internal fans, the speed of the fans depends on the

temperature of internal heat sinks. The air movement is

from front to rear. Allow approximately 10 cms of free

space on front and rear of the instrument, for free air

movement. This allows stacking power supplies one

above other and in 19” rack cabinets. For prolonged life

of the power supply, the inlet temperature of air should

be below 35°C. The instrument control circuit senses

heat sink temperature, power delivered and adjust the

fan speed accordingly. Thus the speed is controlled in

pulsating mode, during this period , high pitch sound is

produced, this is normal.

3.3 Use of instrument on table top

The power supply does not need any additional fitting /

assembly of part. Ensure that the instrument feet are

mounted on bottom side of the power supply unit. If not

using appropriate screw driver, fix the instrument feet ( 4

nos. ) provided with unit.
