WARNING

The following general safety precautions must be observed during all phases of operation, service, and repair of this instrument. Failure to comply with these precautions or specific WARNINGS given elsewhere in this manual will violate safety standards of design, manufacture, and intended use of the instrument. Chroma assumes no liability for the customer’s failure to comply with these requirements.

Verify that the power is set to match the rated inp ut o f this power supply.

Connect the protective grounding cables to a good earth ground to prevent an electric shock before turning on the power.

Never cut off the internal or external protective grounding wire, or disconnect the wiring of the protective grounding terminal. Doing so will cause a potential shock hazard that may cause injury to a person.

Only fuses with the required rated current, voltage, and specified type (normal blow, time delay, etc.) should be used. Do not use repaired fuses or short-circuited fuse holders. To do so could cause a shock or fire hazard.

Do not operate the instrument in the presence of flammable gases or fumes. The instrument should only be used in an environment with ventilation.

Operating personnel must not remove the cover of the instrument. Component replacement and internal adjustment should only be done by qualified service personnel.

1. Overview

1.1 Introduction

Chroma 62000H Series Programmable DC Power Supplies with Solar Array Simulation are high power density power supplies that provide stable DC output and accurate measurement of voltage and current.

62000H Series DC Power Supplies with Solar Array Simulation have the following features: (1) The output can simulate the I-V curve of a solar panel module in the Programming Mode.

(2) Voltage mode with two control loops to provide a stable, quick response output. (3) The ability to set the slew rates of the output voltage and current. (4) High power density output; the maximum output power can be as high as 15kW in a unit

under 3U in height. (5) 16-bit ADC/16-bit DAC to provide excellent resolution. (6) Lower transient spike and transient response time to insure the unit under test receives a

stable output and protection under load variations. (7) Editing mode (Programming Mode) for output waveforms to provide multiple output

voltage and current combinations in real time for extended time period tests. (8) Rotary knob and keyboard controls on the front panel to set the output voltage and

current. (9) VFD panel: a high brightness, wide viewing angle interface for monitoring and setting

functions. (10) Remote control via GPIB/Ethernet (option), USB, RS-232/RS-485, or Analog

Programmable (APG) interface.

1.3 Specifications

Chroma 62000H Series High Power Density DC Power Supplies with Solar Array Simulation offer 2KW (62020H), 5KW (62050H), 10KW (62100H) and 15KW (62150H) m odels based on the output power and the power supply o f each model. Table 1-1 lists the output specifications of the 62000H Series 2KW, 5KW, 10KW and 15KW DC Power Supplies with Solar Array Simulation. Warm up the instrument for at least 10 minutes before performing any test items. The maximum DC Power Supply output voltage must be 5% less than full-scale. All specifications are tested using Chroma’s standard test procedures at 25 ± 5°C, on a remot e sense connection with a resistive load, unless specified otherwise.

2. For switchable power load applications, if the output load cable is longer than 20cm, strand the load cable and parallel the capacitance at the load input to prevent any unexpected oscillation from occurring (see Figure 1-2).

3. For parallel load applications, connect a capacitor of more than 100uF to the load input to avoid any unexpected oscillation from occurring.

Use a brush to remove any dust on it and if there are stains on the chassis that cannot be removed by brush, wipe it with a volatile liquid (such as Cleaning Naphtha). Do not use any corrosive liquid to avoid damaging the chassis. Use a damp cloth with soapy w ater or soft det ergent to clean the LCD front panel. For internal cleaning, use a low-pressure air gun to remove the dust inside or send it back to a Chroma agent for cleaning.

2.2 Preparation f or Use

(1) Remove the iron holder on the front panel as shown in Figure 2-2 and keep it in case the

Power Supply needs to be returned for service. (2) Be sure the Power Supply is connected to an AC line input that meets the speci fications. (3) The instrument must be installed in an area with good air circulation to avoid the internal

temperature getting too high. (4) The ambient temperature should not exceed 40°C.

2.3.2 Input Connections

(1) The input connector board is located on the right side of the rear panel. (2) The power cable must be rated for at least 85°C. (3) The power cable must be within 6AWG-8AWG. (Note: 10AWG-12AWG is required for

the 62020H-150S Model.) (4) See Figure 2-3 (a), (b) to connect the cables to the 62000H. See Figure 2-5 to connect

the cables to the 62020H-150S. Then perform the following steps:

a. Remove the input terminal safety cover from the rear panel of the DC Power

Supply.

b. Scrape off any coating on the power cable tip (the bare portion is about 1cm) and

use an O type terminal to crimp it. (For the 62020H-150S, the bare portion needs to be tinned.)

c. Secure the power cable to the input terminal with a Phillips screwdriver with a lock

torque in the 30-40 (kg-cm) range. (For the 62020H-150S, insert the pow er terminal

and use a Phillips screwdriver to secure it.) d. Lock the safety cover to avoid electric shock. e. Secure the safety cover latch and safety cover to prevent the cable from falling or

the electric terminal from being exposing.

When set to DEFAULT, the output state is set to: V = 0.00V ; I = 0.00A ; OUTPUT = OFF.

When set to LAST TURN OFF STATUS, the instrument will store the last voltage, current

Ex.: In Figure 3-13, the voltage setting is 60.00V, current setting is 10.00A and output setting is ON. When it powers on again, the instrument will restore the previous state by setting the voltage to 60.00V, current to 10.00A and output to ON.

To ensure the control mode remains in a fixed mode, the setting must be larger than 3%.

62000H Series DC Power Supplies with Solar Array Simulation may be connected in series or parallel when in the CV/CC MODE. The maximum voltage is 1200V if connected in series and the maximum current is 250A if connected in parallel. When the IV curve function is enabled in the TABLE Mode, SAS Mode or IV PROGRAM Mode, only parallel connections are supported (no series connections).

A620027 models only support parallel connections.

2. The maximum output voltage or current is 1200V or 250A when operating the 62000H Series with Solar Array Simulation in series or parallel. Table 3-1 shows the values for the 62xxxH-xxxS models.

Chroma 62000H Series DC Power Supplies with Solar Array Simulation have protection functions divided into two classes. The first protection class includes over voltage, over current, over power and FOLDBACK; the second protection class includes over temperature, fan failure and over/under input voltage. The first class of protection trigger points is set by the user as described below, while the second protection class is auto detected by the system hardware protection circuits.

To ent er into the Protection mode:

1. Press “

The remote sense input is located on the rear panel near the output terminal (see section

2.4.1 for the correct connection). It adjusts the power supply’s output so the UUT’s voltag e is consistent with the voltage set on the front panel so the UUT is not affected by the voltage drop across the load wires.

(1) If the connection is wrong, for instance the VOLTAGE SENSING polarity is reversed (the

UUT’s “–” terminal is connected to the “+” of the output terminal and the UUT’s “+” terminal is connected to the “–” of the output terminal), or
