EPOS CV 821-831-753 Specifications

Product catalog summary

Overview: The document provides technical specifications for single-phase and three-phase motor-controlled AC/DC power sources, specifically the EPOS CV 821, EPOS CV 831, and EPOS CV 753 models. These power sources are designed for reliable load applications with manual or automatic voltage settings via ACTAS software.

Specifications:

Voltage and Current: The power sources offer a range of voltage outputs (15-270 VAC, 15-300 VDC for single-phase; 15-300 VACPN, 15-520 VACPP, 15-300 VDC for three-phase) with a step value of 1 V and accuracy of ±1%.
Load Capacity: Rated currents vary by model, with the EPOS CV 821 supporting up to 30 A AC/DC, the CV 831 up to 40 AAC/30 ADC, and the CV 753 up to 25 AAC/32 ADC.
Transformer and Frequency: The transformers have capacities of 8.1 kVA, 11.5 kVA, and 22.5 kVA, supporting DC, 50, or 60 Hz frequencies.
Protection and Regulation: Features include electronic fuses for overcurrent protection and motor-controlled regulation without separate phase control.

Performance:

Settling Time: Varies by model and mode, with DC settling times ranging from 3 ms/V to 42 ms/V and AC settling times from 7 ms/V to 8 ms/V.
Measurement Accuracy: Voltage accuracy is <0.2%, and current accuracy is <0.1%.
Sampling Rate: Ranges from 500 Hz to 10 kHz.

Physical and Environmental:

Power Supply: The systems require 230 VAC ±10% for single-phase and 3 x 400 VAC ±10% for three-phase models.
Housing and Dimensions: The units are housed in 19" racks with varying sizes and weights, from 39 kg to 130 kg.
Operating Conditions: Operating temperature is 0-50°C, with storage temperatures of -20 to 60°C and relative humidity of 5-90% non-condensing.

Compliance: The equipment complies with EN 61010-1: 2011 and EN 61326-1: 2013 standards for safety and EMC requirements.

Appendix: Detailed performance data for operating current, voltage drop, settling time, and maximum switch-on current for each model under various conditions.

Single-phase and three-phase motor-controlled AC/DC power sources for reliable supply to the load applications. The output voltage is set either manually or automatically using the ACTAS software with the aid of variable voltage transformers controlled by servomotors. Output values and operating statuses are clearly displayed on status displays. The power source is short-circuit proof and protected against overload conditions.
