Catalog Description

Doble F2253

Specifications: Note: One unit per phase required.
Mode 1: Source 1 Voltage; 150VA; Range:75,150,300V AC/DC

Source 2 Current: 450VA; Range:7.5,15,22.5,30,45,and 90A AC/DC
continuous.180A maximum for 1.5 seconds.

Mode 2: Source 1 Current: 150VA; Range: 7.5, 15, and 30A AC/DC continuous.

Source 2 Current: 300VA; Range: 7.5, 15, 30, 60A AC/DC continuous.
120A maximum for 1.5 seconds.

Installed Options:
F2810 Fault Rotate: Changes preset voltage and current phasors to
simulate A-N, B-N, C-N, and A-B, B-C, C-A faults without changing
interconnecting leads.
F2820 Delta Value/Delta Time: Simulates rate-of-change in frequency, at
least significant digit Hz per second rates for determining frequency relay
response to actual power system excursions. Also simulates rate-of-change of
voltage/current/phase angle with least significant digit per cycle for
realistic pickup and dropout test using AutoSensE (trademarked). Used with the
 DOB-F2010 Minicontroller (also in the ER pool).
F2875 Battery Simulator: An internal, high starting current 60W
continuous rating DC supply for powering protection relays and auxiliaries.
Select 48, 125, or 250VDC manually or use the POWER macro in PROTEST software.
(included in this configuration).
