DC27 Battery Loads Load Banks.
The DC27 Loads offer the user versatility, flexibility, lightweight, and sturdy design, combined with precise measurement technique to obtain complete battery information, or UPS- and generator characteristic.

Three load types are available: LD260 and LD60 are DC- as well as AC-Loads for up to 600V, 1200A, 100kW; LD100 is a DC-Load for 1V / 100A up to 100V/8A.

Slave Loads: can be series- or parallel connected to Master Load

Battery Load Units measure capacity of back-up batteries by means of a discharge test.
Premature capacity decrease, weak blocks, or weak cells are detected.
Periodic tests assure crucial equipment to run in case of power failure.
DC27 Battery Load Units LD260 and LD60 discharge batteries in the voltage range 10V to 600V at
currents from 1A up to 1200A.
The DC27 consists of a control module and a programmable high current load.
Its versatility is almost unlimited; it performs tasks such as battery discharge without detaching battery,
precise measurements of battery parameters and cell voltages versus discharge, charge estimation
which makes a total discharge unnecessary, on the spot battery analysis, battery data storing for later
analysis on a PC, and finally the DC27 control module analyzes battery systems under float charge,
determines discharging - charging efficiency, and performs step current tests on DC power supplies.

The DC27 control module drives one master load and up to 31 slave loads.
The programmable loads are factory set for 10V-60V/150A -, or 10V to 260V/70A operation.
The weight of a load is only 8.5kg. To discharge high voltage batteries, loads can be series connected.
High current discharge results by parallel connecting slave loads. Load LD100 can discharge single cells, low voltage batteries, fuel cells, or DC-power supplies up to 100A. It operates in the voltage
range 1V to 100V, 800W maximum. Loads can be connected in parallel but not in series.
Analog input and analog output is provided for transient testing or load profile testing.

One master load and one slave load can be connected to form a 50Hz, 60Hz single phase resistive
load for 230V/113A - or 400V/65A operation. The load current is set in the SETUP menu of the control
module. The load characteristic is constant current, constant power, or constant resistance.
Three phase loads, star - or delta connected, can be configured using one master load and five slave
loads.
Maximum power for a basic 3-phase load is 78kW. By parallel connecting slave loads, power can be
iincreased to a maximum of 390kW.
