HOP-1717
The glass ceramic used for the heating surface
is manufactured by the Schott company and is in use in
millions of households. This glass ceramic is highly
resistant to breakage and sudden changes of temp. (a
temperature shock of over 700°Ccan be withstood
without damage), it is also distortion and pore-free as well
as being permeable to ultra-violet light and resistant
against chemicals. Construction: The low-density, glass
ceramic hot-plate, electrically heated centrally over an
area of 145 mm dia., is mounted on a high-grade,
stainless steel housing. The variable temperature control
system is regulated by an energy regulator 10..100%
for temperatures up to 500°C. The energy regulator
is housed in a separate, heat resistant container. Thereby
ensuring that the regulator is not influenced by excess heat
during non-stop operation. A lighted control lamp shows
when the hotplate is switched on. The appliance has a
integrated temperature sensor to safeguard against
overheating. The ready-to-connect hotplate is delivered
complete with a 1.8 m mains cable.

Temperature Range: 20 - 450°C
PHP-4429 is a hot plate with automatic control for precise
temperatures from 20 to 450°C. The required temperature
is preset on the digital regulator and remains automatically
constant, The actual temperature is continuously displayed
with 13mm high numbers. The long-lasting electrical
heating unit can be used in three heating stages - 825 -
1650 - 3300 Watt. Each stage can be finely tuned from 10
to 100% by an electronic output control to prevent
overheating and any after- heating due to excessive
power. The heating stages 825 and 3300 Watt, heat the
total area of the plate. The special 1650 Watt stage heats
only the right-hand section of the plate. Due to creeping
heat, the temperature drops off from the right-hand
section to the left-hand plate edge, by approx. 40%
(temperature decline).
A low voltage 3-pole socket mounted on the right-hand
side of the housing allows the following extras to be
connected (however not conditional):
1. Time switch, for switching the heating unit on and off at
preset times.
2. Contact Thermometer
3. Temperature fuse cut-out
As temperature fuses must have heat
contact, a 4mm diameter hole has been
bored on the edge of the right-hand plate for their
insertion. The heating unit is automatically cut off from the
mains supply after the fuse blows and the contact has
switched to the off position. The fuse has to be renewed
once it has blown.
