Introduction

The Chroma 62000D Series are high power density, bidirectional DC power supplies. These
supplies have regenerative load characteristics with dual quadrant operation allowing energy
feed back to the grid from UUT. They are suitable for testing modern energy storage
systems, providing stable DC output and accurate measurement for regenerative power
applications.
The features of 62000D Series DC power supplies are:
Voltage mode & Current Mode with two control loops  able to provide stable and quick
1.
response time performance. Instruments also provide the ability to program the slew
rate of output voltage and current.
High power density output  the maximum output power can up to 18kW under 3U
2.
height.
16-bit ADC/16-bit DAC  provides excellent resolution for measurement and output.
3.
Lower transient spike and transient response time  Provides for a stable output and
4.
the best protection under load variations.
Editing mode (Programming Mode) for output waveform  provides multiple output
5.
voltage and current combinations in real time for long period tests.
Rotary knob control on the front panel  to set the output voltage and current.
6.
Touch panel  provides users a high brightness and wide viewing angle interface for
7.
manual operation.
8. Via GPIB/CAN (option), USB, Ethernet or APG (analog programmable interface)
interface  to do remote control.
Active PFC design  the PF value of 62000D series DC power supplies is >0.99. The
9.
high PF value increases the distribution capacity and wiring utilization.
10. CP (Constant Power Operating Envelope)  provides for a wide voltage and current
operation. Customers do not need to add additional power supplies to cover low
voltage/high current test requirements.

System Functions

1.2.1 Operation Mode

1. Local operation is performed by the touch panel and rotary knob on the front panel.
2. Remote control is done via GPIB/CAN (option), USB or Ethernet interface.
3. Through the APG input to control output via analog signal.

1.2.2 Protection

1. Protections for voltage phase loss, input over-voltage or under-voltage, output over-
voltage, over-current, over-power, over-temperature, fan fail, CV/CC foldback and etc.
are available.
