Encased protective transformers – isolating and safety isolating – are intended mainly for applications requiring protection against electric shock and IP44 protection grade of the casing. Portable version is provided with a metal casing isolated from the protective circuit and the transformer.PFM encased transformers are cast resin transformers. The electric circuit features the following components: transformer, power cord with a plug, signalling lamp, thermal fuses with pushbuttons, and output sockets. Plugs and sockets are components intended for general applications or CEE type components at request. Grade II insulation class (plug and double contact sockets, 2-wire power cord) type designation code ending with “0”. Grade II insulation class with continuous protective circuit (plug and socket with optional protective contacts connected to a protective wire of a 3-wire power cord) – type designation code ending with “1”.Rated ambient temperature of 25°C, thermal class of insulation B (130°C). Manufactured in compliance with: EN 61558-1, EN 61558-2-4, EN 61558-2-6

Rated voltage PRI: 230V 50/60 Hz
Rated voltage SEC: 24V – 42V or 110V – 230V
Rated power: 1300 – 2000VA at Usec = 24 – 42V; 1600 – 3200VA at Usec = 110 – 230V

Portable transformer for polystyrene cutting is designed to provide the user with the possibility of convenient and precise temperature control of the cutting wire while guaranteeing full safety. The high degree of protection (IP44) ensures that the transformer is splashproof.
The wide adjustment range from 20V to 28V allows to eliminate the negative impact of ambient temperature changes on the working temperature of the cutting wire. The regulation is carried out by 5-position switch with a 2V stroke.

Features:
easy-to-use automatic fuse,
ergonomic, compact design,
comfortable and durable carrying handle,
durable, professional power cord,
power supply indication of the cutting wire with illuminated switch,
comfortable socket for quick connection of cutting wire,
plug included in the set.

Supply voltage: 230V
Adjustable output voltage: 20V – 22V – 24V – 26V – 28V
Frequency: 50 Hz
Power: 250W – max 9A

Plug-in transformers (PFS) and powers supplies (PFLR) intended for supply of professional electrical equipment and commonly used devices. Equipped with protection that enable reuse of transformer after 10-second disconnection. The secondary side has an AMP connection (PFS/PFLR) or conduit with pin (PFLR). Output voltage in PFLR is selected via microswitch at nominal current of 1000mA. Manufactured in insulation class II and protection grade IP33 (PFS) and IP20 (PFLR), max ambient temperature 40°C, thermal class of insulation E (120°C). Manufactured in compliance with EN61558-2-6 (PFS), EN55022 and EN55024 (PFLR).

Power range: 7 – 20VA
Voltage range PRI: 230V 50/60Hz
Voltage range SEC: 3 – 24 V
DC voltage for PFLR: 3; 4,5; 6; 7,5; 12V
