Supports parallel and series measurement modes to achieve high current and high voltage output
- Parallel Measurement Mode
One power supply is set as the master unit while other identical models are configured as slave units. Centralized control is performed through the master unit,
enabling high-current output. (Total output current = Rated output current per unit × Number of units in parallel)
| 400W / 800W |
Up to 3 Units in Parallel (Including Master) |
| 1200W/ 2000W |
Up to 2 Units in Parallel (Including Master) |
| In parallel operation mode, the voltage and current output differences between units are automatically controlled within ±5% of their rated values. |
Supports the series connection of up to two identical units. In series mode, the total output voltage across the load is the sum of the individual output voltages of both power supplies.
(Voltage accuracy follows the specifications of a single unit.)
| Non-series-compatible models |
DCS3104D、DCS3108D、DCS3112D、DCS3120D |
For example, in a configuration with one master unit and two slave units, use the optional TL-DS0004 parallel communication cable.

The MICROTEST DCS-3100 Series features an exceptionally wide voltage and current setting range.
Through flexible voltage and current configuration, it can achieve approximately 3 to 4 times the output range.
By adjusting the voltage and current ratio, the output automatically adapts
Example:the DCS3112A (1200W model) can seamlessly switch between high voltage / low current mode (80V / 15A) and low voltage / high current mode (20V / 60A).

Standard LAN, USB, and RS-232C Interfaces
The MICROTEST DCS-3100 Series comes standard with LAN, USB, and RS-232C communication interfaces.

Built-in 10A Front Output Terminals for Convenient Bench Operation (CAT II Rated, Max. 15A)
MICROTEST DCS-3100 Series comes equipped with front output terminals supporting up to 10A.
Optional safety plugs allow direct front-panel measurement without rack mounting or rear wiring,
providing convenient operation during R&D and design validation stages.

Built-in Internal Resistance Simulation for Battery and Solar Power Analysis
MICROTEST DCS-3100 Series supports an internal resistance simulation function. In CV mode, the output voltage automatically decreases
according to the set resistance value and output current, allowing simulation of internal resistance characteristics of secondary batteries and solar cells.

Supports VMCB Virtual Multi-Channel Architecture for Multi-Unit Control via Single PC
MICROTEST DCS-3100 Series supports the VMCB (Virtual Multi Channel Bus) architecture, enabling control of up to 31 units from a single PC.
This allows synchronized start-up and centralized management across multiple power channels, ideal for automated test platforms,
ATE systems, and multi-rail voltage sequencing for MCU, FPGA, and automotive ECU applications.
Programmable Sequencing and Synchronous Trigger for Enhanced Test Automation Efficiency
MICROTEST DCS-3100 Series features programmable sequencing and multi-unit synchronous operation.Complex test profiles can be pre-
configured and stored for standalone operation without a PC.By sharing a common trigger signal, multiple DC sources of different power
ratings can start simultaneously and operate in coordination,enabling synchronized multi-channel or multi-power output control for higher testing efficiency.
After setup: Even without a PC, different models of the DCS-3100 series can still be interconnected and run synchronously when multiple units are operating in parallel output.
Selectable Bleeder Circuit (ON/OFF) for Safe and Efficient Discharge Control
MICROTEST DCS-3100 Series integrates a switchable Bleeder Circuit (ON/OFF) that provides active discharge capability.
When the output is turned off, it quickly releases residual voltage from internal capacitors or connected loads, accelerating voltage decay and improving testing efficiency.
For energy-storing DUTs such as batteries, the bleeder circuit can be disabled to prevent reverse current flow, eliminating the need for external protection diodes.

Supports Three Start/Control Modes for Stable Output Without Surges
- Output Mode Priority (C.V/C.C)
Allows preselection of constant voltage (C.V) or constant current (C.C) at startup to minimize initial surge risk.
Enables setting a delay after pressing the OUTPUT key, allowing precise control according to load requirements.
Adjustable rise and fall times of output current to prevent inadvertent activation of protection mechanisms due to rapid current changes.

Supports External Signal Control
The MICROTEST DCS-3100 Series supports external voltage and resistance control through analog interfaces. Via the rear panel J1/J2
interfaces, external signals can control and monitor the test power supply.
