Product catalog summary

Overview
The Energy Recycling Load ERI Series provides electronic loads with power capacities from 3,600 W to 10,800 W and input voltages between 120 V and 800 V. These devices are designed to recycle consumed energy back to the local power grid, reducing electricity costs and environmental impact.

Key Features

Energy recycling minimizes waste heat and electricity costs.
Operates silently, suitable for laboratory environments.
Supports constant current, voltage, resistance, and power modes.
Dynamic operation with up to 300 list point settings.
Data acquisition with USB storage capability.
Standard interfaces include Ethernet, USB, RS-232, and CAN; GPIB is optional.

Protection and Safety

Includes protections for current, power, overtemperature, and ground line.
Simple mains supply monitoring is provided.
Touch protection covers for high voltage units.

Cooling and Noise

Energy is recycled rather than converted to heat, reducing air conditioning needs.
Quiet operation due to less reliance on powerful fans.

Interface and Control

Optional galvanically isolated I/O port to prevent ground loops.
SCPI programming with extensive command syntax.
LabVIEW driver certified by National Instruments.

Data Acquisition and Dynamic Functions

Data can be logged to an external USB drive or internal memory.
Dynamic load profiles can be created using a list editor.
Measurement data can be exported and viewed as diagrams.

Model Specifications

Models vary by input voltage (120 V, 400 V, 800 V) and power capacity (3,600 W, 7,200 W, 10,800 W).
Efficiency is approximately 90% across models.
Noise levels range from 55 dB(A) to 59 dB(A).

Technical Data

Reverse polarity protection with diode function.
Accuracy of settings and measurements varies by mode and range.
Dynamic function supports up to 300 load levels with precise timing.
Data acquisition rates and formats are flexible, supporting USB and internal memory storage.

Specifications

Undervoltage protection accuracy is ±1% with a tolerance of ±0.4%.
Input resistance for analog inputs is greater than 10 kΩ.
Maximum GND voltage is ±125 V referred to PE and ±625 V referred to negative load input.
Analog measurement output accuracy is 0 ... 10 with option ERI06, with voltage and current accuracy at ±0.2% and offset voltage at ±15 mV.
Permissible load is greater than 2 kΩ.

I/O Port Specifications

Control outputs include load input on/off, overload, trigger output, and programmable output with selectable voltage levels (3.3 V, 5 V, 12 V, or up to 30 V).
Control inputs include load input on/off, mode selection, trigger input, programmable input, and remote shut-down with input levels from 3 V to 30 V.

Protection and Monitoring

Protective devices monitor overcurrent, overpower, overtemperature, overvoltage, undervoltage, and reverse voltage.

Housing

Front panel color is RAL7035 (light grey), rear panel is stainless steel, and top is RAL7037 (stone grey).
Dimensions are specified in the model overview.

Safety and EMC

Protection is rated at IP20.
Measuring category is O (CAT I according to EN 61010 Rev. 2004).
Electrical safety standards include DIN EN 61010, EMV, CE marking, DIN EN 55011, DIN EN 61326-1, DIN EN 61000-3-2, and DIN EN 61000-3-3.

Options

Data interface ERI02 and GPIB interface.
Hardware expansion ERI06 with galvanically isolated I/O port.
Calibration options include FCC-N-ERI and FCC-ERI.

Payment terms include a 30-day net period, with discounts available for early payment.
Unilateral order cancellation incurs a 30% fee.
Delivery terms include "CIP" with insurance and transport costs charged extra.
Export control compliance is required, with the customer responsible for ensuring no export restrictions.
Packaging is charged separately and should be returned if delivered free of charge.

Liability for Defects

Claims for defects require compliance with inspection and reporting obligations.
Subsequent performance options include defect elimination or new item delivery.
Liability is limited to foreseeable, typically occurring damage unless otherwise stated.
The limitation period for defect claims is 12 months from risk passage, with exceptions for building-related items.

Mechanics / Terminals Energy Recycling The consumed energy is fed back to the mains supply. The operation in the sense of a power generation into the public electricity grid is not provided with these energy recycling loads. The load must be connected to a low-voltage mains supply with a fixed High Power installed and separately fused supply line. The ERI load has a simple and non-redundant monitoring of the power supply. If limit values are exceeded, it switches off the power stage unit. This monitoring does not replace any grid or system protection which must be installed if necessary for the...
