TRANSFORMER 2240
• Double-isolated transformer
• 3 .75 kVAC isolation voltage
• 30 VA ring core transformer
• Thermal overload protection
• 12 or 24 VAC secondary voltage
• Standard 11-pole relay socket
AppLICATIONS:
Transformer for supply of components with 12 or 24 VAC supply voltage .
Transformer for stabilised DC power supplies, e .g . type 2229 .
TECHNICAL CHARACTERISTICS:
Ring core transformer with separate 3 .75 kVAC isolation voltage between primary
and secondary windings . The transformer is fitted with a thermal 100°C fuse .
Two transformers may be paralleled for higher output power . The transformer is
molded into the cassette and should be mounted with 10 mm distance to the
adjacent cassette for optimal cooling .
The load diagram shows the relation between the ambient temperature and
maximum VA output . The module is supplied with a retention clip for a safe
attachment to the relay socket .
MOuNTING:
The 2240 is for standard 11-pole socket mounting in all positions . To achieve
maximum cooling of the module, mounting in a vertical position at a distance of
10 mm between neighbouring units is recommended .
INpuT:
Standard primary voltages of 115 or 230 VAC . Special primary voltages may be
delivered, but are not kept in stock .
OuTpuT:
Standard secondary voltages of 12 or 24 VAC . Max DC power after rectifica tion
and stabilisation: 20 W . Special secondary voltages may be delivered, but are
not kept in stock .
