1.1

Overview

The DP series offers a compact, lightweight, and highly-efficient power system, ranging from
single-phase 1.5 kVA to three-phase 36 kVA at a maximum. It also provides various interfaces such
as the external control input/output, communication interface, and remote controller (some of them
are optional) to address a wide variety of usage. You can configure several products of same
single-phase model to participate in a single-phase three-wire system or three-phase four-wire
system by using a System Cable (optional).
The AC output of DP series ranges from 0 to 310 V for voltage (phase voltage) and 1 to 550 Hz for
frequency, and the DC voltage output ranges from −440 V to +440 V. The maximum output current
(phase current) is 120 Arms continuous (single-phase 12 kVA, 100 V range), and if you use a
capacitor input type rectified load, you can output a peak value of 480 Apk at a maximum
(single-phase 12 kVA, 100 V range, crest factor of 4).

Series Line-up and Polyphase System Configuration

In the DP series, multiple models (single-phase model, polyphase model) are available with various
combinations of output capacity and output phase mode. The lineups of single-phase model and
polyphase model are listed in Table 1-1.
The DP series also offers the Multi-phase model which can switch the output phase mode
(single-phase two-wire, single-phase three-wire, or three-phase four-wire) on a cabinet. When you
set the "phase mode setting switch" of the Multi-phase model and then turn on the power, the model
operates as single-phase model or polyphase model as shown in Table 1-2. The operation
specification, performance specification, and manipulation method of the Multi-phase model follow
those of the single-phase model and polyphase model of the DP series shown in Table 1-2.
The model naming system of the DP series is shown in Figure 1–1.
For the single-phase model, you can connect two or three products of the same model using an
optional System Cable to allow single-phase three-wire output or three-phase four-wire output,
respectively (polyphase system). The polyphase system configurations are listed in Table 1-3.
