Technical Specifications

A) Aluminum profile sturdy flat panel (table top) system, carrying various high voltage components
housed in plastic enclosures (panel) to minimize shock possibility.
– Input 3 phase DOL Starter panel
– 4 pole MCB of 415 V/2A .
– DOL 9A Contactor with 230V / 50 Hz / 11VA COIL .
– Bimetallic thermal O/L relay with range 1.4A – 2.3A .
B) Integrated AC (3/1 phase) measurement panel EMT34 Bidirectional optionally with PC interface & multifunction power meter
– Consist of 2 nos of (96X96mm) Digital meters one each for 3 & 1. Measures V, I, PF (0.2 lag – unity 0.2 lead), Hz. Hence separate analog wattmeters (3, 1) are not needed.
– Current specs for 3 meter = 1.5A (Balanced load) and 1A/5A for 1 meter (170-250V).
C) FWD/REV, Star-Delta starter panel

– Star/Delta switch 3 pole, 3 way with centre OFF, 6A/440V.
D) 3 Phase wound Rotor & Sync. Motor panel
– Rotor resistors of 30E/5A with 3 taps of 0E, 15E, 21E, 30E each ——–3 nos
– Rotor resistor selector switch, 3 pole.6 Way .6A/440 V.
– DC Rotor excitation over current relay (3Amp)
E) 1⌀ Motor, Alternator & Sync. Motor Panel
– 1⌀ MCBs of 4A/1.6A 1 each.
– 2no 2P2W selector switches to run as 1 alternator then as synchronous motor.
– 8A pushbutton switch to simulate as centrifugal switch.
F) DC voltmeter and DC ammeter panel (EMT 6A/6B)
a) DC voltmeter (0-300V)
b) DC Ammeter (0-5A) with polarity protection diode
c) Field failure relay to control Armature supply. Both 6A/6B needed simultaneously.
G) SCR Actuator (variable DC) cum sensor signal conditioning panel (EMT9) [4 Shrouded Banana]
– Full bridge SCR based 0V-195V / 5 Amp cosine firing with linear charateristics.
– Supports signal conditioning circuit for speed, torque in kg wt to output 0-2.5Vdc (FS).
– 3 Nos. of these supplies required for DC Armature, DC motor field and AC generator field.
H) Instrumentation Power supply cum Multichannel DPM panel
(a) +/-12 V, 500 mA (b) +5V, 300mA (c) Unregulated 17V dc/750 mA
